Re: [Windows] Access bridged modem configuration behind/in front
I don’t know if the Linksys can do this, but I have a bridged modem in front of my OpenBSD box/firewall and can access the modem via conditional NAT on the OpenBSD box—and I feel this is the best method for doing this as it does not require any special configuration on the modem. Even though my modem is in bridged mode, it still has an IP—and I have my OpenBSD box configured in such a way that if traffic is going out to the Internet, the OpenBSD box NATs my IP out the public IP, but if traffic is destined to the private subnet between the OpenBSD box and the modem, my IP is NATted out the private IP that’s in the “modem” subnet. With this configuration, I can fully access the modem from any system on my LAN—and do not need to create a route on the modem that points back to the LAN to do so. I doubt the Linksys can do this, but you might be able to get it done with DD-WRT or similar Linksys replacement firmware.
Hope this helps/is not too confusing. If you’re interested in doing something like this, let me know and I’ll provide more detail. |

As I mentioned, I can access the modem ip config pages when it is in bridged mode if I connect to it directly with the computer (setting the computer ip subnet to include the modem ip address). But can't do it with the Linksys in between.
So it's not generally an issue getting to the modem, it's getting the Linksys to route it to the modem.
Is there some reason you think the lInksys can't do this? The link I included indicated it could. I'm not familiar with DD-WRT replacement firmware.

Yes, I'm familiar with that thread. It's very good, but has problems which I've already tested and encountered
1. Doesn't work for single port modems
2. Generates self-flooding of network from modem back up to router, blocking all download activity for about 60-90 seconds, every five minutes or so.
3. One or more of the methods needs another small switch between the router and the modem, requiring more equipment.
4. Doesn't solve the static ip addressing problem I'm trying to solve here.
Thanks, though.
