I'm experiencing a major head-ache at the moment with our company firewall, we're currently changing ISPs (new lease line and new block of static IPs) and I'm setting up firewall rules (we're using a NETGEAR ProSafe VPN Firewall FVX538).
The firewall is visible internally on
126.96.36.199 (all IPs for example only) and we can configure it through the web admin on ports 80 and 443. All traffic from our building goes out on
188.8.131.52, but when you go to the
184.108.40.206 IP (from within or outside the network), the firewall admin page is shown. This isn't really what we want!
I've tried adding firewall rules for HTTP traffic on
220.127.116.11 to be routed to one of our web servers at
18.104.22.168, but when I add this rule, requests to
22.214.171.124 just hang. If I change my rule to
126.96.36.199, it works fine but the NETGEAR admin's still visible on
188.8.131.52 - problem not solved.
The real problem is that this means we can't point our domain
184.108.40.206, because the NETGEAR admin would show rather than our site, but we need this domain to resolve to
220.127.116.11 because all mail out of our building will come from this IP (our client's spam filters won't let our mail through - reverse DNS problems).
I'm banging my head against my desk: this MUST be possible, or how would a company that has a single IP address be able to resolve web traffic? Can anyone help? Sorry if the questions doesn't make a lot of sense - I always find questions like this difficult to express!
Update / Things I've tried
- Ensure remote management is disabled (it's never been enabled anyway) screen
- Rebooted firewall
- Checked for firmware updates
- Tried adding DMZ WAN rule in place of a LAN WAN rule
