SSL VPN issues over 443

I have a /28 block of IPs from my ISP. The external WAN interface of my astaro box is programmed with the 1st usable IP of the block. I added the rest of the IPs as additional IPs on the external interface.

I configured the SSL VPN to use port 443 and attached it to the external interface. Everything worked perfectly.

I then set up two DNAT rules to allow 443 access to two different servers and attached them to 2 other usable IPs of the block. As soon as i created these DNAT rules the SSL VPN stopped working.

What is the proper configuration?

Or better yet, change SSL VPN to use UDP instead of the default TCP

Two thumbs up! Significantly faster that TCP.

I changed to UDP and the SSL VPN work again now. I would have assumed that using 443 wouldnt have been a problem because I was binding the services to different external IP addresses?
