Hi all

I'm having a routing problem which I hope someone can help me solve:

This is a (lengthy - sorry) diagram of our network:

upstream
       |
Cisco 2511 ser1
       |
Cisco 2511 eth0 (192.168.2.217/30)
       |
       | (hardwired via Xover cable)
       |
FreeBSD rl0 (192.168.2.218/30)
       |
FreeBSD rl1 (192.168.0.1/24)
       |
Cisco Catalyst switch
       |________________________
       |                                                     |
dns/mail/www       Cisco1601 eth0 (192.168.0.9)
servers (all on                                    |
192.168.0.x/24)                                 |
       |                                                     |
       |                       Cisco1601 ser0 (192.168.2.229/30)
       |                                                     |
Proxy eth0 (192.168.0.x/24)             |
       |                                                     |
       |                        Rem. Router ser0 (192.168.2.230/30)
       |                                                     |
Proxy eth1 (10.0.1.1/24)                   |
       |                                                     |
       |                        Rem. Router eth0 (192.168.2.129/26)
my workstation                                   |
(10.1.1.4/24)                                    hub
                                                             |
                                various workstations (192.168.2.x/26)

whew :)

Routes added on Cisco 2511 are as follows:
ip route 192.168.2.128 255.255.255.192 192.168.2.218
ip route 192.168.2.228 255.255.255.252 192.168.2.218

Routes added on Cisco 1601 are as follows:
ip route 0.0.0.0 0.0.0.0 192.168.0.1
ip route 192.168.2.128 255.255.255.192 192.168.2.230

This is the route I set on the remote router:
ip route 0.0.0.0 0.0.0.0 192.168.2.229

1. If I telnet to the 1601,
I can ping the remote router ser0 port (192.168.2.230)
I can ping the remote router eth0 port (192.168.2.130)
I can telnet to the remote router (192.168.2.230)
I can traceroute to any of the above.

2. From the 2511 or from my w/s behind the proxy (in the diagram above),
I CAN'T traceroute or ping any of the above. I keep getting bounced between
192.168.2.217 and 192.168.2.218

3. From any of the w/s behind the remote router, I can't ping or traceroute past
192.168.0.9 (1601 eth0). Needless to say I can't surf or pop mail either

So, my conclusion is I need to add a route to the FreeBSD box.

Am I correct? If so, what would be the correct route statement(s) to add?
add route 192.168.2.128/26 192.168.2.218?
add route 192.168.2.228/30 192.168.2.218?

Am I close?

<sigh>
TIA and my apologies again for the lengthy (and newbie post)
