VIP Issue

Hey all,

 

I've setup a couple of VIPs with the same external IP to different internal IPs/networks and different ports on a client's firewall running 6.0.3 (previously 6.0.2).

 

One of the VIPs only listens on TCP 7108 and forwards to a server on the Internal LAN.

The other VIP listens on 22 and is supposed to forward to a server on the DMZ LAN (ftp over ssh).

 

The issue is that traffic to the second VIP never seems to get to the firewall.  I sniff the IP and port 22, or I sniff the DMZ IP and port 22 and see nothing.  The first VIP to the internal LAN works perfectly.

 

If I set the second VIP to use port 2222 (for example) and forward to 22, this works fine and responds.  The issue is that I need the 22 to 22 to work.

 

The client has limited IPs to work with or I'd consider using a different IP entirely.

 

This, to me, appears to be a bug with forwarding SSH.  I confirmed I have it disabled on all interfaces for management, and don't see a specific Local-IN Policy using it or other policy using it.

 

If I enable SSH on the WAN interface, it works - so I don't believe it's the ISP blocking the traffic outside the firewall.

 

Thoughts?

 

Just an odd issue....never had issues with VIPs before.

 

Thanks!

    On further testing, it actually IS the ISP blocking port 22.

     

    I missed it in initial test.

    never had issues with VIPs before.
    - 100 %!

    except maybe for specialities like having a VIP changing an URL to an IP address and thus causing a cert error...even that is solvable.
