i am connecting my ISA server to the linksys router RV042. the router is configured to work dualWan and not DMZ.
i configured port forwarding on the Router, to forward all traffic on port 80 and 443 to be forward to the IP of the ISA. i turned off
the firewall. but no success.
i tested to open http connection to ISA from a laptop connected on one of the LAN port of the router (port next to the port where ISA is
connected) the test is successfull.
another test is done, i installed a webserver application(xerver.exe) on a laptop. i connected the laptop to the lan port of the linksys router,
and i configured port forwarding on ports 80 & 443 to the IP address of the laptop. i tried to connect through http/https to the router ip
address from the WAN but no success. which indicates that the problem is in forwarding traffic from Wan to Lan on ports 80 & 443 and not with the ISA iteslf.
so a configuration option is still missed on the router RV042 to accomplish my setup.
can you please advice.
Dual WAN or DMZ mode will not affect the Firewall rules so long as you are attempting to access the ISA server via the WAN 1 IP address.
You mentioned you disabled the firewall, have you re-enabled the firewall before adding the new rules for port 80?
If not, please do so and report back your findings.
