Static NAT - SA540

Question

Regarding the SA540, Can you can set a statically NAT’d private IP to go outbound on the same Public IP instead of the general one.　 Specifically, 184.183.11.224 routes to 192.168.1.5 and 184.183.11.225 routes to 192.168.1.4.　 Currently, 192.168.1.5 goes outbound as 184.183.11.224 and 192.168.1.4 goes outbound as 184.183.11.225.　 My concern is that the SA-540 isn’t capable of making the latter happen and all outbound communication from 192.168.1.4 and 192.168.1.5 will gout as the Public IP of the router itself (184.183.11.223).
Can anyone answer this for me?

Answer 1

Today we have the same problem,basically we have two public addresses one for internal network another one for mail server.the problem was that we could not inbound from ip address of mail server to alias ip address(not address from main wan interface)
mail server internal ip-------SA540(ip alias address)------internet
network------sa540(main wan interface address)---internet
The solution was to reset to factory defaults and doing the firewall rules for mail server first,i guess somehow SA540 remember old settings(no clear xslate) mostly because of iptables rules or....
