Hi there, First post here, so go easy on me I've been using a Linksys WRT54GS for 6 months or so without any problems. For no particular reason I put a Cisco Pix 501 as my gateway and am now using the WRT54GS purely as an access point, and the Pix for DHCP and as a gateway. All the machines connect fine and browse happily etc - only problem seems to be the DDNS doesn't update anymore because the WRT54GS doesn't think it has an Internet connection. I've told the WRT54GS (192.168.0.254) that it's default gateway is 192.168.0.1 and the routing table seems to reflect this: Destination LAN Subnet Mask Gateway 192.168.0.0 255.255.255.0 0.0.0.0 0.0.0.0 0.0.0.0 192.168.0.1 Any boxes I should be ticking, or is it fairly normal that it doesn't work like this - some of the downloadable apps for Dyndns allowed you to check your external IP if you were behind a firewall, I'm guessing this is what the Linksys now needs to do, rather than using it's own (now non-existant) WAN IP. Using firmware Satori-4.0 v2.07.1.7sv Thanks in advance.
