Hello All
I have two servers - one running MS exchange and the other running a crm platform and both must be access via https. On the router -I have bound https to one ip address and router refuses to accept the binding of the same port 443 to another ip address. I will appreciate any help I can get towards resolving this.
The network diagram is attached.

Hello!
Unfortunately it is not possible to have same port forwarded simultaneously to several internal IP addresses - just imagine even if this setting would be possible, how the router will know which request to which internal server to forward since the port where request was received is the same?
However, with RVS4000 you can do the following - use TCP 443 for server1 and let's say TCP 4443 for server2.
Let's assume that your servers have the following IP address assignement:
Server1 - 192.168.8.100
Server2 - 192.168.8.101
In RVS4000 go to Firewall -> Single Port Forwarding
Configure it as on the screenshot:
After that you can access from the Internet both servers using the following URL:
Server1 - https://wan_ip_address
Server2 - https://wan_ip_address:4443
Hope it will solve your problem!

I agree with Ivan on this, once you bind a port to an ip address that is all it can do. However if you wanted to keep the internal 443, you could create two external to internal mappings and change the external port your accessing. \
For example: 5000 external 443 internal mapped to ip address a.b.c.d, and 5001 external 443 internal mapped to ip address e.f.g.h.
