UTM 9 using Sophos IPSec Client and OTP....VPN re-key causes session to drop

I have had problems like what you describe, but had not identified a root cause.   Session stops working, seems to be in limbo between connect and disconnect.   Have you contacted support with your evidence?  You may have found a bug.

Hi Douglas,

Yes the case is open with Support.

The issue only occurs when using OTP in the password element, I'm guessing its because the re-key meets an invalid OTP element.

Using a static local password allows the tunnel to stay up without issue.

Hi, 

Please PM me your case# in Support. 

Cheers-

My problem is with SSL VPN, and happens faster than the rekey interval.   So I am pursuing the issue separately with support.

Hi All,

What I am experiencing is confirmed by support as a limitation of the UTM when using an IPSec tunnel.

Using OTP for Xauth will result in the tunnel dropping during re-key.

The only option is not to use OTP.

SSL VPNs are not affected by this issue.
