In our office we use a Linksys BEFSR41 as our router/firewall, and we have a webserver outside the firewall. Today I set up webdav on the server and when we tried to connect the weirdness started. We can still ssh to the server and reach it via pop and smtp, and the rest of the world can reach port 80. But ever since we tried mounting the webserver with davFS on one machine, none of the machines behind the firewall can reach the webserver on port 80 (port 443 works fine).
No filterswere added, nor is their anything odd in the router set up. I have tried power cycling the router a couple times.
Still, nothing can get through to the webserver on port 80, though the outside world can reach our server and we can reach other webservers.
Any idea what is up? My thought is the Linksys is to blame, but like I said before, it's config looks good and it has been reset a couple times.
