Testing an IPX tunnel (very slow)
Help... have to make a IPX tunnel through a ip only network. Got it working on a Cisco 2600 but having issues on a 2500. I think I have just missed something somewhere. Here is my config

The router that this traffic passes through (the ip only network) is simpler with the following config: I know the Tunnel is correct on the other end because my 2600 has no problems. I have to make this work on both 2500 and 2600's because we have over 65 sites and both routers are currently used in the field.

Here are the oddities about this...
1. When I install a new router with this config (2600 or 2500) it seems to run real slow. A telnet session takes a good while to connect... even one router away... BUT, about 30 min later or so and it becomes normal (like the routes take that long to update).
2. An IPX pc on the 40.120.43 network (between the two routers above) loads the novel script extremely and painfully slows. After it does load... the computer does not show up in the show ipx server list.
I'm at a loss here. It works for the 2600 but I did have the same issues there as well. Seems to be a routing or routing update issue. I'm not sure. Please help I'm not a Cisco genius and my super is looking to me to make this work... this is a test bed for a very large project that needs to be completed right away.
Thanks!

****I have set the pc to auto detect all ipx types

Somebody has got to see my error here... anyone?
It only causes this behavior (slow) when you create the tunnel on a 2500?
Is the first config you posted what you're doing with the 2500?
How much memory is on the 2500?

Yes, I have it working well on the 2600. But have not been able make this work correctly on the 2500. The only real changes were to the interface names and some routing details but I cannot figure it out. I'm thinking I made some errors... but I was hoping for an expert eye to look over my config and see if there was any noticeable mess ups. I can’t find it.
Memory - I will post this ASAP

What about this statement though
ip classless
ip route 0.0.0.0 0.0.0.0 Ethernet0
ipx route 0.0.0.0. 0.0.0.0 tunnel20
I'm not sure if its correct for this configuration. It was just an attempt to make it work. On my 2600 there are 2 ethernet ports and the ip route was only pointed to the interface without the tunnel on it. On the 2500 there is only one ethernet interface and so I pointed the ip route to it, and no ipx route.
2600 route
!
ip classless
ip route 0.0.0.0 0.0.0.0 Ethernet1/0
It maybe that the 2500 just cant do this job...

Hey Don guess what...
I had tested this on two 2500 routers and it failed. I just got in another 2500 from a closed location and tested it again and it works fine. Now I just have to isolate the issue to IOS or memory or just crapy equipment.
Thanks for your help
