Simple port forward (smtp) stop working after upgrade from 4.0 to 5.0.12 (FGT80C)



I have a little problem with upgrade proccess...


After upgrade firmware on FGT80C from 4.0 MR3 patch 18 (b. 689) to 5.0.12 (b. 318) one of the "simple" (as i was thinking) policy stop working. 

It's simple because it's only forward port 25 from exteral ip to local mail server.


Why after upgarde it's stop working?


I have saved config file before and after upgrade and tried to compare them but i dont see anything special (maybe i dont know where to take a look)...


Right now i have downgrade to 4.0, restore config and everithing works just fine (so it's no urgent...)


Best regards

Create a new one, change it in the policy and delete the old one.

Also check your Service (SMTP here)


maybe one or both of the objects got corrupted

Esteemed Contributor III

In the policy where you apply the VIP, do you specify "ALL" as service, or "SMTP"?

Background: in some v5.0 firmware the "ALL" service definition was flawed. Maybe you could check it (you can edit pre-configured definitions as well as custom ones).
