IPSec and multicast. Dynamic IP.

[Tyler Hardison <thardison@modbee.com>]

Hello all,

I have successfully setup isakmpd on two openbsd machines, and I have two 
questions:

1. One particular piece of software we use locates a login server through 
multicast (not microsoft), it basically contacts: 233.1.1.2 which is a 
metaserver for our Unisys publishing system.  The IP range on one side is 
192.168.80/24 and the other side is 172.17.48/20. Any advice on this?

2. Eventually we'll be implementing these VPN boxes at remote locations 
behind dynamically assigned IP space (ADSL).  I have set this up before for 
my home firewall/server (openbsd of course) with great success. But I need to 
know how to tie this in with isakmpd. Hostnames?

Thanks for any advice or help you can provide. Even pointing me in the right 
direction for docs would be great.

Tyler.
