i have been working on this for over a week with no luck - if i configure the web server in my dmz to listen on port 5000 i can forward requests coming from outside on port 5000 and everything works fine. if i configure the web server to listen on port 80 and try to forward port 80 i get nowhere. what could be reason for this. i don't have any access lists that would block traffic on port 80. in fact all i have is:
access-list outside_in extended permit tcp any host <public IP> eq www
access-list outside_in extended permit tcp any host <public IP> eq 5000
static (dmz,outside) tcp interface www 10.10.5.13 www netmask 255.255.255.255
static (dmz,outside) tcp interface 5000 10.10.5.13 5000 netmask 255.255.255.255
like i said - with port 5000 everything works fine but not with port 80. any suggestions? thanks in advance...
