As these kind of questions pop up regulary in the support forum, eventually it could be worth to discuss if in a future release more VPN protocols should be supported.
Currently (3.9.3) there are those two support:
- Cisco; Cisco means the “old” Protocol used by Cisco PIX, which is essentially IPsec. Can be used to connect to many different IPsec capable gateways like AVM or Lancom.
However, there are a few other protocols which are even at least as popular:
- L2TP; Used for example by Dell UTM; Debian has
network-manager-l2tp-gnometo support it.
- Cisco Anyconnect; The “newer” Cisco protocol, which is essentially SSL VPN; used not only by Cisco but also Juniper and some VPN services; Debian has
openconnectto support it.
What are your opinions on it?
