Having problems with an ifconfig alias for VPN. Its for an ipv4 bind address.
To set the alias address im using:
$ ifconfig ppp0 alias <bind ip address> <vpn gateway remote addr>
netmask 255.255.255.0
Is ifconfig is calling out to pppd daemon to set up the alias address?
It seems packets send to the alias address 111 appear on the ppp0
interface. But not to
go to the right destination. Perhaps some ipfw /
packet-rewriting rule is needed?
janitors-Mac-mini:peers id$ sudo tcpdump -i ppp0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on ppp0, link-type PPP (PPP), capture size 65535 bytes

If its any help, I would be happy to post some further logs and info
about this particular case.
