[Openswan Users] IPSec/L2TP problem

['james']

Hi, 

 

I would like to set up a Linux IPSec/L2TP VPN server with the following
software:

 

Fedora Core6 with 2.6.18

 

Openswan 2.4.13 

 

xl2tpd-1.1.11

 

 

The ipsec connection is fine, but at the l2tp connection procedure, when the
client (behind a NAT server with public IP 74.13.213.134) send SCCRQ control
message, the server side report error:

 

packet from 74.13.213.134*:4500: recvfrom 74.13.213.134:4500 has no Non-ESP
marker,

 

Then the client time out:

Connection 0 closed to 74.13.213.156, port 1701 (Timeout)

 

It seems the server don't accept UDP ESP packet.

 

Any solution?

 

Thanks

 

 

Best regards,

 

James
