pfSense

For PPTP clients DNS fails, I get a DNS time out, on every IP on a pfSense interface for which DNS is configured including the PPTP server IP. I have a PPTP Client to any rule and can connect to other DNS servers without issue through any pfSense Interface. I am not seeing any errors in the VPN, Firewall or System logs that explain what is happening.

I have no issues using DNS services on pfSense interfaces from local IPs or from clients on the other side of an IPsec tunnel. I have not yet tested for this issue with a Mobile Client IPsec tunnel.
