Cisco VPN Client not route after update 9.409-9

tcassano

Hi,

i have updated my Sophos UTM SG310 to the version in subject.

Before i did the update I could get access on every network devices over Ipesc Cisco with the iPhone of my company.

Now after the update I'm not able to do it anymore.

The Connecting and the authentication are ok (VPN Connected) but I can't ping any device on any network (Request timeout).

SSL and PPTP works fine.

 

Can somebody help me about this issue ?

 

Tommaso

    Hi Tomasso,

    Does #1 in Rulz give any hints?

    Hi bob,

    the VPN connection is establishing and I didn’t see error on firewall logs. Everything looks working but i can't ping or browser my network.

    I thing that is a bug because I saw other reports in the community with the same issue.

    I'll try the suggestion made by Alex and let you know if it works.

    Thank you all to your support.

    Hi,

    I observe same/similar problem.

    I am trying to setup Cisco vpn client access between my UTM 9.409-9 (running in a VM on a machine behind a Fritzbox)

    and my iPhone S6.


    IPSec SA is established but ping traffic is dropped.

    When I use use 'cat /proc/net/xfrm_stat' I see the counter 'XfrmInStateProtoError' increasing.

    Do you know what that counter means?

     

    I also dumped the traffic following the instructions here:

    https://community.sophos.com/kb/de-de/116179

    I can see the decrypted icmp packets as expected. Only strange thing in the wireshark analysis:

    Under Encapsulating Security Payload I find

             --> 'Authentication Data [incorrect, should be ....]'

    I am not sure though whether this is the cause or whether I put the wrong information in field  'Authentication key' of wireshark. The instructions say: 

    • Authentication key: enter the preshared key used to encrypt the tunnel. Eg. test

    I do not use preshared key. I use certificates. Do you know which value should be used in that case for the Authentication key?

     

    Thanks and BR,
    Michael
