Disappearing DNS resolution via VPN on SnowLeopard

Disappearing DNS resolution via VPN on SnowLeopard

Ever since upgrading to Snow Leopard, I find that my DNS lookups go pear-shaped after 2 minutes or so. To be precise, I stop being able to resolve names that are only resolved by the specific servers delivered by the PPTP server, as opposed to the ISP's hosts. Apparently, something is overwriting the servers from the PPTP server with other hosts. Anybody got a way around this?

"Snow Leopard seems to have broken DNS settings from VPN connections. It worked fine in Leopard.

As a band-aid, I put two scripts in /etc/ppp: ip-up and ip-down. I use them to save the current DNS, change it to the VPN dns, and when disconnecting, change it back.

It's ugly but works.

/usr/sbin/networksetup -setdnsservers ""Interface Name"" [ip of dns server]"

You can manually edit /etc/resolv.conf, maybe.
