[vpnc-devel] vpnc-nortel can establish connection but doesn't receive any traffic

[Dick]

I did some more debugging and I'm afraid ESP traffic is blocked at the
concentrator. I've tried --natt-mode cisco-udp and --natt-mode force-natt but
vpnc keep sending ESP packets (I found this by using tcpdump).

I'm using the following config:
IPSec gateway 1.2.3.4
IPSec ID 1234
IPSec secret 5678
IKE Authmode gpassword
Xauth username 9012.3456 at abc.de
Xauth password 7890
Vendor nortel

Could someone please tell me what I'm doing wrong?

Thanks in advance,
Dick
