I got it to work exactly as you suggested using isakmpd.conf. It took me quite a bit of searching to find the correct sort of syntax for that file to achieve what I wanted but it now allows me to connect.
But I've run into another issue that I cannot resolve myself. Once I connect from ANY client, I can only move data on the VPN for a few seconds then it goes dead. I thought it might be an MTU issue, but I tried setting the MRU setting fairly low (such as 1200) in npppd and that didn't solve it. I tried setting skip on enc0 as well as pppx0 in pf rules and that didn't work either. What else could I be missing? Why would it work, but only briefly? Sly
