I'm using smoothwall as a firewall that somes right after my cable modem in the network. Smoothwall is then crossover'd to my router's WAN port, and the router DHCP's to computers from there. I would like to administrate smoothwall via PC -> router -> smoothwall, but for some reason, it's not letting me connect. If I pull the crossover cable from the router and plug it into a computer, I can administrate smoothwall just fine. So there's something about that router that's either blocking my connection or modifying the packets in a way that smoothwall refuses the connection (but those are just my guesses). What can I do to get this working?

Hi.. came across your post when I was searching for an answer to the same question - did you resolve this, and if so may I ask how?

Thanks

SmoothWall includes a DHCP server, why is the router needed?

I want to install a Linksys Wireless Broadband router between my PCs and the Smoothwall box. Being new to DHCP administration I am struggling to avoid DHCP conflicts between both devices. The Smoothwall install is still configured to offer DHCP services but since adding the WRT54G I now have a second device offering DHCP (which I know can lead to conflicts). I tried the WRT54G 'DHCP disable' option but that resulted in me losing browser access to the router altogether (which could only be resolved by a hard reset of the router back to factory defaults). But with the router restored and once again automatically assuming DHCP services it means I can't access Smoothwall's ADMIN functions from my PC's browser 'through' the new router to Smoothwall's 192.168.1.1:441 (or :81). Like ORANGE400, I have to take the router out of the loop and run my GREEN connection direct from Smoothwall to the PC. Once I have finished the admin functions I then re introduce the router into the GREEN loop, but naturally I don't want to keep doing this.

Maybe a crash course in TCP/IP network addressing & subnetting, majoring in multiple DHCP Servers is ahead of me! Or a post to Linksys on how to successfully disable DHCP on the WRT54G without losing browser access to the router's config pages!

Thanks

If smoothwall is plugged into the router's wan port, it really shouldn't matter if they're both running dhcp servers or not, as long as the wan port on the router is on a different subnet from the other ports on the router.

Basically, my suggestion is that you should have one subnet (192.168.2.0, 10.0.0.0, whatever you want) just for the router's wan port and smoothwall's lan side. Then you give another subnet to the lan side of the router. That way, smoothwall's dhcp would only be serving the router, and the router could serve dhcp to your network. Just make sure that none of the router's ip addresses are the same as any of smoothwall's ip addresses, or you'll never be able to access it directly, even though normal routing works fine.
