l2tp problem spoofed packets

Danik
Hello

I have a problem after astaro updated to version 8.201, VPN L2TP problem.

Clients can connect to VPN but can't access any port ... can't ping the internal IP's


The firewall show this message when the client tries to connect to an destination port:

14:56:53 Spoofed packet TCP 192.168.1.3:52185→192.168.1.22:22 len=53 ttl=64 tos=0x00

Please help ...

PS: Sorry for my bad english

    It will decrease your security slightly, but keep in mind that Astaro uses multiple techniques to protect you (firewall rules, flooding protection, IPS etc.).  This is only a temporary solution until the problem is fixed, hopefully in the upcoming 8.202 up2date patch.

    Sorry to dig up an old thread, but was this problem ever fixed?

    I've updated an ASG220 from 7.511 to 8.300 yesterday, and starting today not one of our PPTP-VPN users was able to connect to our Terminal server via RDP.

    The Firewall-log showed that all attempts were dropped because of "Spoofed Packets"...as soon as I disabled Spoof Protection they were able to connect.
