I have two external public IPs that used to be mapped one-to-one to two internal private IPs. Now, I want to get rid of one of my internal servers but I want to continue to use my two public IPs but both going to the same server.
Can I do something like this:
static (outside,inside) xxx.xxx.xxx.xxx 25 192.168.7.7 25
static (outside,inside) yyy.yyy.yyy.yyy 110 192.168.7.7 110
So incoming SMTP traffic to the "x" public IP goes to the same server as POP3 traffic does when it is sent to the "y" IP.
Also, since the SMTP server is also going to be sending out email, will I need another "static (inside,outside)" translation for outgoing traffic too or will the previous translation do the outgoing traffic also?
for example, do I need a:
static (inside,outside) 192.168.7.7 25 xxx.xxx.xxx.xxx 25
(or have I got my IPs reversed?)
