Answers

General

1. Why can I not connect to my ISP even though my router's WAN
light is on?

 Verify that your interfaces are actually up by entering the Monitor mode and listing the configuration of the router. View the status of the interfaces listed that are actually up. Check your IP addressing scheme by verifying that your IP addresses are configured correctly by entering the Monitor mode under the IP protocol and using the interface and static commands.

Verify that your route statements are correct.

2. How do I set a default gateway.

At the IP configuration prompt, set the default network gateway:

IP config>set default NETWORK-GATEWAY

3. How do I set a static route?

 At the IP configuration prompt, add the route:

IP config>add route

4. Why can I ping my router's Ethernet port but cannot ping
beyond that point.

 Make sure you have the correct default gateway configured on your workstation or server. The gateway for your local LAN is the router's Ethernet IP address.

5. Why can I not ping an address that I changed on one of my
router's ports?

With the exception of static routes, you must restart your router for any configuration changes to take effect.

*restart

6. How many IP addresses can my router's Ethernet and WAN
ports support?

 16 addresses each

Modems

7. What should the modem init strings be set to?

 OpenROUTE Networks recommends that you use the modem initialization commands shown below for the following modems:

Notes:

The commands shown above have the following meanings:
Command Meaning
&F Resets the modem to factory default settings.
E0 Disables modem echoing of commands.
M0 Turns off the modem speaker.
S0=1 Answers on the first ring in auto-answer mode.
&B1 Sets the modem serial port speed to the speed at which the last AT command was issued.
&C1 Turns CD on when the modem connects, off when the modem disconnects.
&D2 Causes the modem to hang up when DTR is turned off.
&H1 Enables hardware (RTS/CTS) flow control.
&K3 Enables hardware (RTS/CTS) flow control.
&B115200 Sets the modem's serial port speed to 115200 bps.
\\Q3 Enables hardware (RTS/CTS) flow control.
&S0 Sets DSR always on.
\r Sends carriage return to the modem at the end of the initialization string.

8. Why does my GT 60 Series router not send the init string to the
modem, and why does the list devices command show the
device connected to the modem to be in a Down state?

Some modems (for example, the Hayes Optima) have Carrier Detect set to ON as the default. The GT Series router expects to see Carrier Detect set to OFF when there is no connection. To correct the problem, do the following:

1. Connect the modem to a PC serial port.
2. Run a terminal emulator.
3. Enter AT. Be sure you get an OK from the modem.
4. Enter AT&C1 to set the modem to bring up Carrier Detect only when there is a connection.
5. Enter AT&W to write the change to memory.

9. What speed should I set the GT 60 Series router serial port to?

10. How do I set up dial-on-demand?

1. Disable RIP on both the GT 60 Series router and at the remote site. To disable RIP on the GT 60 Series router, enter configuration at the * prompt to display the Config> prompt and then enter the following commands: 
Config>protocol ip
IP config>rip
RIP config>disable rip
2. Set the idle time on the dial circuit to the amount of seconds of idle line usage before the call is disconnected (60 seconds is a good value). At the Config> prompt enter network # (where # is the number of the interface that you are configuring) to go to the Circuit Config <NET-#> prompt . Enter set idle. 
Config>network 1
Circuit configuration

Circuit Config <NET-1>set idle
Idle timer (seconds, 0 means always active) [60]?
Note: You must restart the router for this configuration to take effect.

11. Which boot code does async dialup require?

The minimum boot code supporting async dialup is 1.10.

12. What modem signals should I see using the list interface
command at the + prompt?

It depends on the type of connection:

13. How should I set the modem's flow control?

 The modem should be configured for CTS/RTS flow control (not XON/XOFF).

14. Can I connect using a synchronous modem?

Yes. You can make several kinds of connections using synchronous modems:

15. What if my modem only returns numeric result codes?

Set up the GT 60 Series router to understand numeric result codes as follows: 

Circuit Config <NET-1> dial
Serial Interface Dialer Configuration
DIAL Config <WAN>modem modem_name
Modem Config>set result-code ok 0
You can also use the set result-code command to change other result codes, such as connect or busy.

Note: You must restart the router for this configuration to take effect.

16. Which signals does my modem have to support in order to
interoperate with my GT 60 Series router?

17. What does the Serial Interface Dialer (DIAL) assume for modem
support?

 DIAL assumes that the modem configuration

18. What modems have been tested with the GT 60 Series router
for V.25 bis?

19. What modems have been tested with the GT 60 Series router
for synchronous (non-V.25 bis) operation?

20. What modems have been tested with the GT 60 Series router
for asynchronous operation?

21. Why is my CHAT script not transmitting properly?

 When creating a transmit CHAT script, make sure you add a \r (for carriage return) at the end of each transmit character string.

22. Why is my CHAT script failing when I have the correct
information in it?

The first character in a string that a GT 60 Series router receives from a remote system may be case sensitive, and you may wish to ignore the character when you do not know what the case of the first character is. Using the wrong case in a CHAT script causes the CHAT script to fail and the connection to be terminated. For example, a Login prompt might be Login: or login:. If you do not know the case of the first character, then enter the string in the receive command as ogin:.

A simple login CHAT script may look like this:

Receive: ogin:

Transmit: OpenROUTE Networks\r

Receive: assword:

Transmit: test\r

Interoperability with a Livingston Router

23. How can I make PAP authenticate with a Livingston PM2
Portmaster?

 When running PAP with a Livingston PM2 version 1.31, the PM2 does not accept a request from the remote router as Authenticator. OpenROUTE Networks recommends that you upgrade your software on the PM2 to version 3.3.1. This should take care of this problem. The password on the Livingston unit must be the same as the password on your GT 60 Series router.

24. How can I make CHAP authenticate with a Livingston PM2
Portmaster?

When running CHAP with a Livingston PM2 version 1.31, the GT 60 Series router and the Livingston PM2 must have the same secret.

25. What are the PPP LCP settings when connecting to a Livingston
PM2 Portmaster?

Note: You must restart the router for this configuration to take effect.

Interoperability with a Cisco® Router

26. How can I make PAP or CHAP authenticate with a Cisco 250X
Router?

The password on the Cisco router must be the same as the password on the GT 60 Series router.

Interoperability with a Xylogics Remote Annex

27. How can I make PAP authenticate with a Xylogics Remote
Annex?

Set the following port parameters on the Xylogics Remote Annex:

1. user_name: [enter remote name]
2. port_password: [enter remote password]
3. slip_ppp_security: N
4. ppp_security_protocol: pap
5. ppp_username_remote: [enter local name]
Set the following global parameter: enable_security: [enter N]

28. How can I make CHAP authenticate with a Xylogics Remote
Annex?

Set the following port parameters on the Xylogics Remote Annex:

1. user_name: [enter remote name]
2. port_password: [enter remote password]
3. slip_ppp_security: N
4. ppp_security_protocol: chap
5. ppp_username_remote: [enter local name]
Set the following global parameters:

1. enable_security: [enter Y]
2. chap_auth_name: "[enter local name]"

Interoperability with a Bay Networks Router

29. How can I make PAP authenticate with a Bay Access Node?

 Set the following port parameters on the Bay Access Node:

1. local authentication protocol: papauth
2. local pap ID: [enter remote name]
3. local pap password: [enter remote password]
4. remote pap ID: [enter local name]
5. remote pap password: [enter local password]

30. How can I make CHAP authenticate with a Bay Access Node?

Notes:

1. The Bay AN has problems with X.21 DCE.
2. DTE runs okay on the Bay AN but the GT 60 Series router configured for DCE to Bay AN does not work.
3. Not tested, because router models used did not support async PPP.
4. You must use software version 3.3.1 or better on the Livingston to make PAP work on calls originating from the Livingston to the GT 60.
5. Cisco doesn't support PAP and CHAP at the same time on one interface.
6. The Xylogics RA2000 does not learn the GT 60 Series router's RIP routes due to a problem in the Xylogics software. The GT 60 Series router learns the RIP routes from the Xylogics RA 2000. To work around this, do the following: 
IP config>set broadcast
Set interface address [0.0.0.0]?50.2.88.45
Use a NETWORK or LOCAL-WIRE style address [NETWORK]?local-wire 
Fill pattern for wildcard part (0 or 1) [1]?1
7. RIP/SAP on the Xylogics RA2000 does not interoperate with the GT 60 Series router due to a problem in the Xylogics software. The problem prevents interoperability with IPX in general between the Xylogics and the GT 60 Series router.
8. You must have the same password on both the local and remote router, and you must have both routers in each other's access list.
9. You must have the same secret on both the local and remote router, and you must have both router in each other's access list.
