Cant see other network from public IP

[demonmaestro]

I have two public IPs. One is assigned to the WAN. (1.2.3.4) and the other is set to virtual IP to a 3rd NIC(opt2)(5.6.7.8).
Problem is I have a computer that I want to talk to on 5.6.7.8 from 1.2.3.4
Right now I do have a rule on the 3rd NIC to not allow it to talk to the LAN

How do I get this computer to talk to the server on 5.6.7.8?

Just for testing. I had disabled the rule for opt2 not to talk to LAN. Still cannot ping or anything from the LAN to the OPT2.

I got it figured out.
I had to add a rule after the block to allow the certian IPs
