[OpenIndiana-discuss] IPNAT redirection.

[Jonathan Adams]

more specific addresses to forward:

root at oldfluffy:/etc/ipf# ipnat -l
List of active MAP/Redirect filters:
rdr iprb0 n.n.62.35/32 port 143 -> 192.168.0.12 port 143 tcp
rdr bge0 192.168.0.65/32 port 143 -> 192.168.0.12 port 143 tcp

List of active sessions:
RDR 192.168.0.12     143   <- ->n.n.62.35    143   [n.n.180.45 34032]

and even if I change the port so there is no possibility of conflict:

root at oldfluffy:/etc/ipf# ipnat -l
List of active MAP/Redirect filters:
rdr iprb0 n.n.62.35/32 port 144 -> 192.168.0.12 port 143 tcp
rdr bge0 192.168.0.65/32 port 144 -> 192.168.0.12 port 143 tcp

List of active sessions:
RDR 192.168.0.12     143   <- -> n.n.62.35    144   [n.n.180.45 36138]

neither worked ... I can only assume that I can't port forward in this way,
and will just go back to using "delegate".
