For testing purposes, I am trying to connect 2 PC's on different
subnets via a Win 2003 server with Routing and Remote Access.

I have the following setup:

PC1         ip:        192.168.254.1
        subnet:        255.255.255.0
        dgway: 192.168.254.252

Win2003 Server
        nic1:        ip:         192.168.254.250
                subnet: 255.255.255.0
                dgway:

        nic2:        ip:        192.168.253.254
                subnet:        255.255.255.0
                dgway:

PC2        ip:        192.168.253.10
        subnet:        255.255.255.0
        dgway: 192.168.253.254


On 192.168.254.252 is our Cisco PIX firewall through which we connect
to the Internet.

I understand I need to add a static route to the firewall, so I have
added:

route inside 192.168.253.0 255.255.255.0 192.168.254.250

I am unable to connect PC1 and PC2 together. I can from PC2 to
192.168.253.254 and 192.168.254.250.

It has been suggested to me that I need to allow ICMP redirect packets
in the rules on the firewall. However I am unsure with the exact
command to use.

Any help or other suggestions would be appreciated.

Martin

Does PC1 also have a route to 192.168.253.0/24 via 192.168.254.250?
