I am setting up a new router with NAT. I have 2 WANs, one static, one dynamic (secondary internet connection).
The static WAN connection has gateway internal & external address, plus 16 additional IP addresses set up in DNS for different services, on different internal servers. Internal servers all have 10.x.x.x IP addresses.
In the previous router, I could add all 16 aliases to the WAN, and then use them in the firewall configuration to ensure the wan-lan communication.
However, the dlink dsr-500 only appears to allow max. 8 IP Aliases (when adding the 9th, the interface dropdown only has 'optional WAN', and saves as 'WAN 2' - when i edit that IP alias, i can pick 'WAN 1' again, but it says that the maximum aliases have been added.
Alternatively, could i use Routing to direct traffic from the wan (static IP address x.x.x.215 to 10.x.x.25, for SMTP, for example)? When i try adding this rule, it says 'Selected interface does not have a valid IP address' (unless this means a different issue...)
Question: is there a way to add more than 8 IP aliases? If not, what am i doing wrong with the static routes?
