PF + IPsec

[Cristian Cardoso]

I tried as follows without success:

rdr on xn0 inet proto icmp from 10.31.32.67 to 10.0.0.0/8 -> 10.19.12.251
nat on xn0 inet proto icmp from 10.0.0.0/8 to 10.31.32.67/32 -> 10.19.12.251
rdr on enc0 inet proto icmp from 10.31.32.67 to 10.0.0.0/8 -> 10.19.12.251
nat on enc0 inet proto icmp from 10.0.0.0/8 to 10.31.32.67 -> 10.19.12.251

xn0 is my interface that goes to the internal network that is beyond
the freebsd and enc0 of the vpn, I just put the icmp protocol for
testing
I checked on tcpdump on the enc0 interface, which occurs echo request
and echo reply, but does not return to the PC that ran icmp on another
network within 10.0.0.0/8

Any suggestion?
