PIX 515 port forwarding (ssh) with existing NAT
Posted on 2006-11-27
I need to allow external access (from a static network address ie. 100.100.0.0/16 and via a random static port, ie. 6000) to port 22 (ssh) on an internal server using PAT.
I currently have a PIX 515 with a dynamic NAT rule enabled, translating all outbound office traffic using the outside interface IP. I also have a dynamic IPSec policy with accompanying access-lists (including split-tunneling) operating to allow VPN connections.
When I typed in this command to get started...
static (inside, outside) tcp interface 6000 10.10.10.10 22 netmask 255.255.255.255
...all outbound web traffic was cut off, as was the ability to connect using the VPN client.
Must I create the access list first and have it ordered AFTER the existing ACLs? Should I append the access rule to an existing list before I create the static PAT rule? How would this be done?
