Forefront TMG - Outbound IPSec Connection gets blocked
Posted on 2010-01-07
I've just installed the new TMG. Well, so far everything works fine.
Except some outbound VPN connections doesn't work.
I've checked the tmg event protocols and it shows me that following connection is dropped:
Client IP - Destination IP - Port - Protocol - Result Code
192.x.x.x(local) - 212.x.x.x(extern) - 4500 - Ipsec NAT-T Client - FWX_E_FW_IPSEC_DROPPED
The status message says:
Status: A packet was dropped due to periodic inconsistency between the IPSec policy and the Forefront TMG snapshot of the IPSec policy.
I already added a rule which allows all outbound traffic from internal network.
So why does it drop this connection?
Thanks in advance!
