Naturally :) But that leaves the problem of not being able to add non-existing interfaces to a zone. Let alone define any rules for those interfaces. Meaning the l2tp users are being confined to a tunnel with a dead end if I use the default DROP policy. As far as VMware overhead is concerned, I've used P1-66 upto P4-700 and now it's on a Quadcore together with some more or less publicly exposed services. I've never noticed any difference in internet speed, except for that one time I'd set up a honeypot out of interest. ;) > I have >> found no other way to handle this other than by setting the policy for >> iptables to ACCEPT.

Again I'd have to guess. Can't realy pinpoint the origin. In any case restarting ipsec only doesn't help. It would seem the part that's causing the problem stays resident, but I can't find it.
