[Openswan Users] ipsec_nat_encap used!?!

[Stephan Mischnick]

Hi,

can somebody tell me why ipsec_nat_encap is used? I think this should 
only be used, if nat-traversal is used.
Compilation of the module is successfully done but loading it, dmesg 
alway reports that
ipsec: Unknown symbol ipsec_nat_encap

if I comment out the use of ipsec_nat_encap in
ipsec_mast.c
ipsec_tunnel.c
the module crashes...

what is wrong?

Stephan
