Hey guys,
i have a problem with one policy. this policy works on th wireless interfaces. the policy should accept smtp and smtps. Webfilter options are only email filter and deep inspection.
but i cant send mail! when i check the traffic log, smtps traffic is deny. why? i have the same polices on the wired lan and there the policy works!
First the log and second pic is the policy
can someone help me out? what is wrong?
cheers raffa
thanks in advanced Rafael

What does the full event log message say? You can drill down into the event/packet to see why it was blocked. (see attached example.) Could you can provide a screenshot of the Firewall policy in question?

hey dave thanks for the answer...
sorry for the wrong infos --> i've done the smtp/smtps policy only with the email-filter! the web-filter is deavtived on this policy!
thanks in advanced Rafael
Event doesn't give an actual message as to why NBD0282 is blocked. I see Threat#131072, Threat Score 30, Tran Display noop, Threat Level high. Googling Threat 131072 brings up TR-Agent.131072.BH.trojan though. So I am guessing NBD0282 is infected.

Cheers dave,
i've made a scan for this trojan, found nothing...but i find one thin very strange. when i connect this Notebook to the wire LAN with the same policy --> smtp / smtps allow with email filter --> it works! only the same wireless policy doesn't.
puuhh made a sniff from wireless lan

thanks in advanced Rafael
hey guys,
i opened a ticket! ...will report.
cheers raffa
thanks in advanced Rafael
did you manage to resolve the issue, how? I am having a similar issue, no response from support so far.
thanks
The policy has the device type as 'samsung tablet' while the OS of NBD0282 is Windows. Just wanted to confirm if these tablets are windows, and if the FortiGate is detecting them correctly?
Have you tried the policy without the device specified (only source address) to see if it works?
Can show us the diff between policyid 17 vrs the other policy that works?

hey guys,
sorry for the delay...i resolved the problem with the support!
what we did;
1. we upgrade the firmware to the beta...
2. made some sniffs with the forti technican
3. i send the config to the forti technican to test it in the lab
and the solotions was....i deleted the policy, booted the firewall and created the same policy with the same credentials again...
after that the policy worked! :)
strange but true
