Can't bring natd to work in the "internal" interface.
Have to run the natd on the internal interface.
Scenario:
PC1 pc2
PC3
10.10.14.13/24===10.10.14.254/24(rl1) 10.0.0.214/24(rl0)===10.0.0.254
gw 10.10.14.254 gw 10.0.0.254 route
10.10.14.0/24 10.0.0.214
Ping from PC3 to 10.10.14.254 ok
PC3 to 10.10.14.13 ok
Ping from PC1 to any interface ok
So adding in pc2:
ipfw add 300 divert 8668 ip from any to any via rl1
/root # ipfw show
00100 7830 313200 allow ip from any to any via lo0
00200 22 968 deny ip from any to 127.0.0.0/8
00300 8 672 divert 8668 ip from any to any via rl1
65535 107693 17501832 allow ip from any to any
and
natd -v -i rl1 -reverse
natd[1316]: Aliasing to 10.10.14.254, mtu 1500 bytes
In [ICMP] [ICMP] 10.10.14.13 -> 10.0.0.254 8(0) aliased to

No Packets are coming back.
But:
natd -v -n rl1
natd[1321]: Aliasing to 10.10.14.254, mtu 1500 bytes
In [ICMP] [ICMP] 10.10.14.13 -> 10.0.0.254 8(0) aliased to
[ICMP] 10.10.14.13 -> 10.0.0.254 8(0)
Out [ICMP] [ICMP] 10.0.0.254 -> 10.10.14.13 0(0) aliased to
[ICMP] 10.0.0.254 -> 10.10.14.13 0(0)
Natd leave the packets untouched and can ping from PC3 to PC1 and PC1 to
PC3
How to analyze?
Tried tcpdump.
What I am missing?
