GRE Tunnel over NAT?

trazxtrazx Member

Hey guys anyone know how to setup a GRE tunnel between a lowend NAT server (ipv4 nat) and a normal server (with ipv4)?

I found a tutorial by BuyVM which is pretty good but it's meant for a GRE tunnel between ipv4 and ipv4 server ...http://wiki.buyvm.net/doku.php/gre_tunnel

any help would be appreciated!

Thanks

  • Would require GRE module loaded in the hostnode, which is probably not enabled.

  • Humm, I see, so GRE/IPIP modules are not usually loaded by default?

    My basic goal is to connect my main server to my lowend NAT server so that I can forward particular traffic from my main server to the NAT server and back

    Had a ticket with @quadhost about 9 months ago about the very same issue. They said they were going to test enabling the modules, and depending on testing roll it out. Not sure if that ever got anywhere.

  • Ah I see that's a shame ( I'm also using a quadhost nat server)

    Did you find a workaround/solution to tunneling traffic between your servers?

    Thanks I appreciate the help

    Why should IT be for all OpenVZ VM's by default? On our range for example I can count on one hand the number of users that have requested it.

    GRE can be enabled on request via ticket.

    Open a ticket and ask us to grant your container the correct permissions.

  • Hey i-83, that's great! yeah I don't know enough about GRE --I just assumed it was loaded by all kernals by default. Anyway happy that you are offering to enable it by request! Many thanks

  • Not sure, how I would forward though since the buyvm tutorial requires an ipv4 ip address---I could try IPV6 to IPV6 but I'm pretty sure the instructions in the link I provided would need to be different

    Thank you for the help

    Just out of my own curiosity, if you don't have huge amounts of traffic, why not leverage something like OpenVPN for this instead of GRE?

  • Humm, i don't know about huge...half a terebyte or so...openvpn is a good idea, I haven't considered it tbh--I've always seen it as a tool to connect between client and server, not server and server if that makes sense...I'm clearly a bit of a noob, do you have any thing that can point me in the right direction? I appreciate the help!
