Hello. I am in a bit of a conundrum with setting up an Edgerouter X unit running EdgeOS 1.9.0 for our company.
We have two public IP addresses 208.x.x.26 and 201.x.x.27 that I configured on eth1. Both public IP addresses are routing to the same subnet on eth2-eth4 which is 10.x.x.0.
Any traffic using the .26 IP works fine, things like standard internet access and port forwarding to our ticketing system and WSUS setup. We provide monitoring services to our clients that try to contact our servers on the .27 address due to it being a whitelisted IP for SMTP traffic. The problem is, anything trying to use that .27 address fails to communicate, and I am lost as to why. I can ping the address both inside and outside the network.
I attempted to use NAT/firewall rules as shown here on the UBNT forums without any success.
I appreciate any help with this, as getting this .27 traffic flowing is the only hiccup I am experiencing with this setup.
