I have a cisco 5510 with the old 8.2(5) system running on it. Id like to be able to pass ssh traffic from a server in the DMZ to a server on my lan.

DMZ Server : 192.168.250.230.
LAN Server: 192.168.3.201

What commands do I need to accomplish this?

Here are my interfaces.

interface Ethernet0/0
 nameif outside
 security-level 0
 ip address x.x.x.194 255.255.255.224
!
interface Ethernet0/1
 nameif inside
 security-level 100
 ip address 192.168.0.1 255.255.252.0
!
interface Ethernet0/2
 nameif dmz
 security-level 50
 ip address 192.168.250.1 255.255.255.0
!


My ACLs are called

access-group acl_out in interface outside
access-group inside_access_in in interface inside
access-group acl_dmz in interface dmz


Relatedly, I made an external A record for servername.mydomain.com and pointed it to the external IP, then a couple of commands in my ASA

access-list acl_out extended permit tcp any host x.x.x.198 eq xxx
static (dmz,outside) x.x.x.198 192.168.250.230 netmask 255.255.255.255

where xxx is the port we used, and that seems to work. Once connected to that machine though  I cant then ssh into a machine on my LAN.
