And we, the list, probably more so. :)
I haev a firewall iptables on FC3. It was reciently pached to include
support for pptp. When one of the users (who has a linux desktop) tries
using pptp, the firewall crashes .. (the entire box panics). Any ideas
how one user could bring the firewall down .. I need to fix this somehow
Is the firewall machine the one running pptpd? If so then your
assumption that it was "bad packets" hitting netfilter would appear
premature. Check your logs, do debugging of the more likely suspect, pptpd.
. THis problem does not appear when windows users attempt to use pptp.
And do yourself another favour ... dump PPTP. It's lousy and inherently
not secure. OpenVPN ( http://openvpn.net/ ) beats it in every way. The
only limitation is that it won't work with old DOS-based Windows
versions, but then, it's rather reckless to support those in a business
setting anyway IMO.
