Hi,

I set up a VIP service + Port Forwarding + Policy in my SSG5 but for some reason it's not working.

- I have one public IP address
- Two VIP services: One for port 8111 and one 3000. 
- Both are using the same interface IP address (untrust eth0/0 = 38.104.xxx.x)

- I'm trying to get VIP service for port 3000 to be accessed externally. (e.g. tester.intentmedia.net:3000 to point to 192.168.6.130:3000) 

Attached are my firewall configs

I can reach the VIP service for 8111 externally and locally but I can't reach the VIP service for port 3000 externally.

What am I doing wrong? Any suggestions or help would be appreciated.

Thanks.

Hi,

The configuration looks good.

Please confirm if IP 192.168.6.130 is Up and running and is reachable from the FW.

If yes, then look at the policy logs and check if you see any traffic.

Event logs can be checked for any VIP related errors.

Later a debug can be run to check the traffic.

1. undebug all

2. clear db

3. set ff dst-ip <vip-ip> dst-port 3000

4. debug flow basic

5. initiate traffic

6. undebgu all

7. get db st

The output should show the traffic handling by firewall.

Regards.

Hardeep

If my post is helpful, please mark it as accepted solution so that otherc can benefit from it.

Thanks for this. 

I found that the server isn't pingable within the FW. I'll check to see if ICMP is enabled then continue troubleshooting. 

Thanks again. 

Does the server's IP address need to be pingable in order for the VIP service to work? It's reachable via SSH and browsing 

Could there be a routing issue? 

Thanks in advance. 

there is an option "server auto detection".  if this is enabled, then pings to the server must be successful, otherwise the vip is disabled.

making sure that this is not enabled will allow the vip.

in CLI, it's the "manual" option at the end.:

set interface ethernet0/0 vip interface-ip 21 "FTP" 192.168.1.33 manual

That got it working, thanks! Status is up and everything is reachable. 

Many thanks for the assistance. 

Cheers!
