I've connected to internet by Beeline (Russian internet provider) -- 100 baseT ethernet cable at home.
The provider supports this scheme only:
1) Computer receives internal IP by DHCP protocol (10.x.x.x), gateway and 2 DNS servers. In good old times there was internal provider resourses and P2P communications available in this internal provider network, now it is not available... but scheme is so nowdays.
2) Computer establishes PP2P connection to server resolved by name(!), vpn.internet.beeline.ru, by example. Resolved PP2P server IP can be changed (round-robined), so it is really need to resolve PP2P server by name.
3) Computer receives (in PP2P session) real dynamic IP, other DNS servers and gateway, and ready to communicate with Internet.
Does pfsence support this scheme?
Thank you all for answers.
