Routing Questions

[ashrobbo]

Hi Guys,

I'm struggling here and need a bit of help.

We recently installed a watchguard 510, all is well (kind of).

We have 2 sites, one (HQ) on 10.0.0.0 and one(leamington) on 10.0.1.0 Leamington has a cisco 1841 its side (10.0.1.1) this connects over a serial link to our HQ Router (10.0.0.220).

The IP on each serial interface is 50.0.0.1 and 50.0.0.2 respectively.

Watchguard is 10.0.0.1

Servers on 10.0.0.0 have there gateway set to the watchguard (10.0.0.1) I have a route on the watchguard for 10.0.1.0 to sent to 10.0.0.220.

HQ LAN ---> Watchguard -->HQ Router-->Serial Link<--leam Router---Leam LAN


Now:

I can ping anything from hq lan->Leam Lan

I can also ping anything from the Leam LAN that doesnt have a gateway of the watchguard.

Routes on HQ Router look like this:
ip route 10.0.0.0 255.255.255.0 10.0.0.1
ip route 10.0.1.0 255.255.255.0 Serial0/2

Routes on Leam Router look like this:
ip route 10.0.0.0 255.255.255.0 Serial1/0

Watchguard Routes:
Route to: 10.0.1.0/24 via 10.0.0.220

My google skills are failing me, I remember learning 'if you wish to route between routers, each router must know about the networks it isnt connected to, a router automatically knows about the networks that are connected'

Thanks in advance!

e-cookie for the solution finder!!

edit: if i set a persistent route on any of the computers on the HQ to got 50.0.0.1 end this works, but id rather not

Just an update, i solved this by plugging in our HQ router directly into a port on the firebox and configuring it as a trusted port. it appears either the cisco or the firebox cant route back through its own port?
