@Pete-S said in Firewalling IPsec tunnel traffic?:
So in summary, you can accomplish the same thing, set up a VPN tunnel and limit traffic over it, with both IPsec and OpenVPN but in slightly different ways.
Correct. But "slightly different" is so slight, that it is just the tools used. Like can you use a cardboard box or tupperware to transport your marbles from point A to point B? Yes. Both "work the same" as in that they are boxes that you place things in. What is different is just one has a plastic top that you "peel" open, the other has interleaving flaps. The differences are in how you "set them up", but not in what they do.
So in that way they vary like Windows and Linux vary. Both work in the same places, do the same things, but they just have different configuration commands and interfaces.
