I'm trying to ssh from the outside world into one of my servers. I gave three interfaces on the PIX, ouside, inside, Vlan5. Vlan5 being on the outside of my privated network. The server is on Vlan5. It as a public ip. Here is what I have in the access-list for this connection,

access-list outside_acl permit tcp any host [server-ip]eq ssh

I can't ssh from home into it. The PIX is also connected into a 6509 switch not being used as a route, but it has it own access-list. The PIX connects to the inside interface to the swtich. Also the PIX connects to a router on the outside interface. Both servers are on the same subnet.

Thanks

I have another server also with a public ip that works fine. It has the same access list rule as the other server that does not work.

Any ideas??
 
Do you have "STATIC" mapping for this server

something like

Code:
static (Vlan5,outside) global_IP private_IP netmask 255.255.255.255 0 0
 
Yes, I do. I even try doing the (inside,outside)
 
Strange thing about it is that the server that works doesn't have that entry.
 
Can you ping this server from the firewall? Can this server reach the outside world? Do you have any access rules blocking outgoing traffic on this interface?
 
I can ping within the firewall to nthe server. I can't go out to the world and I can't find anywhere where I am closing traffic on the interface
 
Also, we have a outside router, from there I can ping the one server that works likes call it serverA, but I can't ping the other server (serverB). Again, they are on the same subnet. There is a route on the outside router via the inside interface that goes to the PIX. (ip.0/26)
 
Can you please check the servers gateway and subnet mask.

Your first task is to make sure the server can actually see the outside world, then can post your config, obviously you need to remove anything that is sensitive.
 
The gateway and submask are correct. I can see the world also. The PIX has to much sensitive data, I'm not aloud to give it out.
 
Just scrub it before you post -
remove all passwords
Sub in a.b.c.### for any external IPs
Change/delete the domain name

I'll get back on this later, my configuration is over 300 lines.
 
I got it working, it turn out to be a server issue. I do however have a problem where I will lose connection on the ssh, by doing a clear xlate, it comes back. I have to do this onces a week. Is this normal?
 
Sounds like you might have resources issue, does this affect only this server?
