Make partially specified permanent links without `dst_addr'
but with `dst_port' work for outgoing packets.
This case was not handled properly when I first fixed this
in revision 1.17.
This change is also required for the upcoming improved PPTP
support patches -- that is how I found the problem.
Before this change:
# natd -v -a aliasIP \
-redirect_port tcp localIP:localPORT publicIP:publicPORT 0:remotePORT
Out [TCP] [TCP] localIP:localPORT -> remoteIP:remotePORT aliased to
[TCP] aliasIP:localPORT -> remoteIP:remotePORT
After this change:
# natd -v -a aliasIP \
-redirect_port tcp localIP:localPORT publicIP:publicPORT 0:remotePORT
Out [TCP] [TCP] localIP:localPORT -> remoteIP:remotePORT aliased to
[TCP] publicIP:publicPORT -> remoteIP:remotePORT
