NAT Errors

Kindly do exact same test case which caused NAT errors in earlier versions.

Ok, I'll set up a L2TP/IPSEC server in the next days.

However, I've just tried generating some p2p traffic using μTorrent and some errors has been logged:

01/01/2011 : 08:43:12 UTC : :Delete Private Entry Protocol 17 Failed

I'm using CANOPY 13.4.1 (Build 6) SM-DES

Thanks for confirming, So all your did have AP-SM in session and SM has NAT enabled , SM has internet access and you tried to download some torrent file using uTorrent , no vpn or anything in between , Right?

Yep, exactly.

As shown by the logs, the error occurs using applications that are UDP-based (that's why I did a test with uTorrent).

After one hour of torrent transfers, another error has been logged

Thanks, We will try this test case in our lab.

We have identified the root cause. This will be fixed in next build. Thanks,

No, please wait for build 8.

Some errors has been logged on a customer radio, he's using a IPSec VPN.

However since the update the SM is no longer crashed, this is the only error logged in 4 days.

Is there steps to reproduce it everytime?
