In the server-config: push "route 212.83.129.0 255.255.255.0". Can you add a log from a client connecting?

comment Debian Server Unexpected Crash
To me looks like an error in the filesystem (syscall fastpath, RIP in spin_lock), but I suspect an error in the system's RAM. Can you run memtest for some hours?

Is /etc really on /dev/sdb2?

comment Openvpn, forward packets very slowly
In your tcpdump, I don't see slow traffic (it might be too short tho). Every client gets the same ip-address 10.8.0.2? Can you omit that and rather push a route to your network 212.83.129.0?

No dot means append domain here, while . at the end means not to do this.

comment DNS failure for wildcard subdomains
Isn't there a dot missing at the end, so it's "*.example.com."?

The cron output should go to /var/log/syslog. What do you see there?

comment How are cellphone IP addresses assigned?
If you happen to have an Android phone, you can check your local IP in settings -> status, it's most likely 10.x.y.z. Then visit whatsmyip.org to see your public IP. Then compare it with a friend's phone who has the same provider.

comment Linux - TCP Source Port Reuse (and delay)
Looking again at this, the tries #1..#3 are SYN-server while #4 is SYN-client? Or is that a typo?

Check with wireshark or tcpdump on both sides of the firewall if the dhcp-requests go thru.

The cert that apache is trying to access is intentionally not there or should it be elsewhere?

comment assigning write permission to /proc/sys/vm
I've looked into the first 2.6.28, and it was already present there, too. So it should be working.
