I've got poptop sort of working on my OpenBSD 3.3 box, but I'm running into some problems. I can get it to authenticate (only with chap, I assume that has to do with the openbsd ppp) and windows conciders it connected to the network. Once it's connected I can't ping anything besides my ip. I was reading though some faqs (the faqs were for linux so this may not apply) and it said there were problems with pppd and proxy_arp, but I should be able to ping the pptp server. I can't ever get that far. Any one using it and have it working. Here's the contents of messages

I'll post the configs later if anyone thinks they can help, I don't want to post too much spam.
For the time being I don't care about it only authing with chap and the lack of encryption, but I would like to make ms-chap-v2 and mppe-128 work eventually if any one knows the way.

I found I need to take psudo-device gre out of the kernel. Will it work?, I won't know untill its done compiling. Just how long does it take a p1 233 to compile an openbsd kernel, I'm already runing out of other things to do and its not even done making depend yet.
I found the answer I needed http://lab.digitol.net/openbsd-poptop.html Its now working perfectly with ms-chap-v2 and mppe-128 and I am quite happy. (I can now move the wireless segment off my cheesy windows ras server.. yay)
