I would also highly recommend that you do not use port 22 for ssh from the outside ... pick a non standard port (like 3333 or 22222, etc.) and add this option as well to sshd_config
port 22 port 3333
You can then port forward port 3333 from linksys to 3333 on your centos machine ... you can ssh in via that port from outside and still use port 22 from inside your firewall (via other machines inside your firewall). (you will also need to open up port 3333 tcp on iptables if you have iptables on).
What about simply forwarding a non standard port from my Linksys router to port 22 on my CentOS system? This way I wouldn't have to reconfigure anything except for the router itself.
If you linksys will do that, yes it is perfect ... mine has very limited port forwarding capability ... it only forwards a port (say 22) to the same port on one machine.
No way to set more than 1 external IP or port forward 3333 -> 22 ... 3333 -> 3333 only and 22 -> 22 only. That is how mine works :(
