Subject: Re: [Openswan Users] NAT-Traversal issue
Hi Ozai,
It could be that the router that is in front of the client that is trying to connect is altering the packages with IPsec-passthrough functions. Sometimes this breaks the connection and it is better to turn these features off. You could try to connect directly and see if that works. On the openswan 2.6.38 computer, what kernel version do you run? And which linux distribution? And the NAT is done by which device?
Greetings,
Bart

Dear Sirs,
The messages are from server.It seem that client did not transform the IP address.So the server can not check antyhing.It seem the NAT traversal could not work.What kernel feature do I need to enable?or anything else I need to check?
Can someone point me in the right direction?Please help,Thank's.
Best Regards,
Ozai

Subject: NAT-Traversal issue
Hi Sirs,
I setup a openswan VPN client behind the NAT.The test environment is as below.
It did not work.The traffic did not seem to pass to server.
I got a message like "NAT-Traversal: ESPINUDP(1) not supported by kernel for family IPv4".
It seem the NAT Traversal issue.What kernel feature do I need to enable?or anything else I need to check?
Can someone point me in the right direction?Please help,Thank's.
