I have a Vigor 2862 router with FTTC on WAN1 with 8 IP addresses. It is all setup and working and I have added the other IP addresses in the appropriate place in the Internet Access settings. I have DMZ the second IP address to an RDS server and ports 25 and 443 are forwarded from the router WAN ip address to a mail server offering OWA on 443. All went well until I tried to log onto OWA which worked and then onto RDS which didn't. Long afternoon later I found that if I turned off the 443 forward to the mail server the RDS works. If I re-enable the 443 forward to the mail server RDS gets sent to the mail server IIS not the RDS IIS, which are different. So I can't have 2 https sessions coming into the router on different IP addresses at the same time. Has anyone come across this and solved it?
