[support] Re: [Dsmip] NAT Traversal is not working as mentioned in DSMIPv6 draft

[manish Jamwal]

Thanks Seb for quick response.

Yes, I need this feature and willing to look further into daemon code to
come with solution. Need some starting pointers from you. Currently I
have two question in mind.

a. If BU packet is getting UDP encapsulated in IPv4 network, then why not
the BA getting encapsulated in UDP. I think both BU and BA, will use the
same UDP encapsulation/decapsulation code, then why the behavior is not
same.

b. UDP encapsulation is implemented in kernel. So the changes to support
encapsulation of BA will require kernel changes also?
