OK, it was obviously not Parallels, but some "feature" of the network I was trying it in (Wifi with 802.1x authentication). After moving to a simpler network, I get a network connection from the VPS.

Now I'm struggling with the firewall within the VPS. I've set the HN's firewall to be transparent for the VPS, which works fine. If I now switch on the firewall in the VPS (which is CentOS 4), I can't connect to the VPS via SSH, despite allowing SSH traffic in system-config-securitylevel. It looks like the rule generated by system-config-securitylevel for allowing incoming ssh connections is never matched (so the next rule REJECTs the incoming connection). If I simplify the rule (in /etc/sysconfig/iptables)

-A RH-Firewall-1-INPUT -m STATE --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

as generated by system-config-securitylevel to

-A RH-Firewall-1-INPUT -p tcp --dport 22 -J ACCEPT

and restart the firewall, I can connect to the VPS via SSH. However, I have about 5s delay after entering the password before I get the shell. This delay just goes away when I'm shutting down the firewall within the VPS.

I'm using kernel 2.6.18-8.el5.028stab031.1 and vzctl 3.0.16 on CentOS 5 on the HN and a CentOS 4 template on the VPS.

Any ideas whether this is a problem of the kernel or some mis-configuration?
