Static Route Setup Problem

[mudtoe]

Hi folks:

I'm having a problem with setting up a second subnet on my home network. For reasons too complicated to go into here I need to put a second router on my home network. I currently have a Netgear MR314 with firmware version 3.29 as my primary router. It's IP address is 192.168.0.1 with a subnet mask of 255.255.255.0 . I'm adding an SMC 7004ABR router with firmware version V.1.41.004. I've assigned it a static IP address of 192.168.0.251 on the WAN side of the router, and an IP address of 192.168.123.254 with subnet mask 255.255.255.0 on the LAN side of the router. Visually it looks like this (I've only shown 1 PC on each router for simplicity):

PC1 (192.168.0.250)
|
|
|
MR314 (192.168.0.1) <---------- INTERNET --------->
|
|
|
| (192.168.0.251)
SMC7004ABR
| (192.168.123.254)
|
|
|
PC2 (192.168.123.186)


I setup a static route entry in the MR314 that looks like this:

Destination IP Address: 192.168.123.0
IP Subnet Mask: 255.255.255.0
Gateway IP Address: 192.168.0.251
Metric: 2

I verified that the route was enabled.


When I do a ping or tracert from PC2 (192.168.123.186) to PC1 (192.168.0.250) everything works fine. However, when I do a ping or tracert from PC1 (192.168.0.250) to PC2 (192.168.123.186) it times out. The tracert from PC1 to PC2 looks like this:

1 1 ms 1 ms 1 ms 192.168.0.1
2 4 ms 2 ms 2 ms 192.168.0.251
3 * * * Request timed out.

The tracert from PC2 to PC1 looks like this:

1 1 ms 1 ms 1 ms 192.168.123.254
2 4 ms 2 ms 2 ms 192.168.0.250

Trace complete.

Both PC1 and PC2 can access the Internet correctly. I'm not sure what I haven't setup correctly. Suggestions or advice welcome.

OK. I think I may have figured out what the problem is, but if so I don't know how to get around it. Could the problem be that because NAT is enabled on the SMC7004ABR router, it doesn't like seeing it's internal addresses (192.168.123.xxx) coming in from the WAN side? If this is the problem does anyone know how to turn off NAT on this router? There didn't seem to be anything on the web administration interface to do it. I'm not sure if the serial port can be used to do more administration type things on the router, or if it's just for a modem to be used as an ISP backup.
