Sure, that's why I wrote "and others compatible with OpenVPN like pfSense, OpenWRT etc" in the first paragraph. Jim Thompson wrote: > > Performance is better with IPsec. Because it's in the kernel?

IPsec in itself maybe a standard, but IKE does not seem to be much of a standard, I get the impression that there's much incompatibility between vendors (Cisco, racoon etc). -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN AS43859
