[Asterisk-Users] SIP phones with dual ethernet.

[Chris Clifton]

ipsec vpn's. cisco's pix 501 is cheap and works well for the home office

That way the * box just appears to be on a different subnet as far as the
phone is concerned. nat'ing becomes a non-issue.

At least that's what we plan to do.
