- 2.6.22dr1 indeed fixes the ipsec0/mast0 thing, now even when 
nat_trav=yes, I see netif_rx(ipsec0) instead of (mast0) in debug and VPN 
- seems like i no longer have the inactivity problem (when no trafic 
through VPN for hours, must down/up tunnel)

I did have to apply ftp://ftp.openswan.org/openswan/testing/nat-t/*, 
otherwise it seems to search for old style natt (which fails because 
make nattpatch fails on K2.6.25), while you replied "No" to my question :

No. <<----

Can this NAT-T patches stuff be cleared ?
