  Hi, all.

I don't understand why i need to create dir out policy for transit
ipsec traffic?

For example(conf from 192.168.77.1; it acts as a gateway between world and
private network behind 192.168.77.35):

ip xfrm policy add src 192.168.77.35 dst 0.0.0.0/0 dir fwd tmpl src 192.168.77.35 dst 192.168.77.1 proto esp reqid 1 mode tunnel
ip xfrm policy add src 0.0.0.0/0 dst 192.168.77.35 dir fwd tmpl src 192.168.77.1 dst 192.168.77.35 proto esp reqid 2 mode tunnel

doesn't work. But:

ip xfrm policy add src 192.168.77.35 dst 0.0.0.0/0 dir fwd tmpl src 192.168.77.35 dst 192.168.77.1 proto esp reqid 1 mode tunnel
ip xfrm policy add src 0.0.0.0/0 dst 192.168.77.35 dir out tmpl src 192.168.77.1 dst 192.168.77.35 proto esp reqid 2 mode tunnel

works well.

May be anybody can help me with this?

Thanks!
