Server rentals :: NFOservers.com

Hello Everyone,

I run PPTP servers and they use server side NAT to delegate the IP addresses. I have a standard setup I apply to CentOS across different VPS providers and never run into issues.

With NFO it seems the NAT will not work. It does not do it's job at all, I have tried disabling SELinux and IpTables to Troubleshoot and it is no help.

I can get 1 IP setup working, no NAT. I can add the additional IP's fine but NAT doesn't function.

It also seems there is a TTL Issue, I get major issues, if I run this it fixes TTL problems (of course this is a sloppy solution)

iptables --table mangle --append PREROUTING --in-interface eth0 --jump TTL --ttl-inc 1

Anybody come up with a solution for NAT issues?

Thank you

I wouldn't expect for you to need to change the TTL unless you want to hide your "hop". Where are you seeing a problem with the TTL?

What iptables lines are you using to configure the NAT?
