WEB ACCESS FROM DMZ THROUGH PIX FIREWALL
Posted on 2006-10-30
I have a strange problem in that i have 3 servers sat on the DMZ which can all access the web ok. I have added another, but although this can ping the local network and can be accessed externally i can not get the server to access the web.
The pix is connected to a linkproof loadbalancer, but there are not access rules set on this unit.
I can see in the log of the loadbalancer that the ip address of the server is getting through to it, but does not make it as far as the router. or so it seems.
The server is added to the pix as a host and all rules are host based, so i shouldnt need to add any extra rules to the access list.
If i take down one of the servers and use this ip addres on the new server it works fine.
I can only assume that there is a problem with the firewall in that it is not letting something through somewhere.
