I need to buy for a client a router that supports GRE tunnels. It must not exceed 300 usd.
the tunnel type is GRE, no keepalive, no key.
i want to replace the linux box that acted as a gateway until now, with a router that is decent at routing a 30 PC computer network (10 mbps line).
I would prefer linksys, but something else that is available in Europe will do just fine. Please post if you tested it, i cant get something that doesnt work. saw the linksys rv042 but read on some forums that it doesnt support this, just plain ipsec.
Thanks a lot

please guys, can anyone help me? thanks

**** set up WIN2000 server as a vpn server,,and use WRT54G to passthrough VPN to this server,,be advised that some versions of the WRT54G don't natively support GRE Protocol 47 traffic...
Make sure you enable PPTP Pass Through (ie. GRE Protocol 47 traffic) on the router. From a V8 device (and should be similar on earlier devices)...


*** however: If your WRT54G is a Ver. 5 or later, you won't be able to use it for your vpn server because these models do not support passing "PROTOCOL 47" (uppercase for emphasis ) or "GRE" as it's commonly referred to.

The Linksys routers that do pass GRE with "native" firmware out of the box are the following:

1) WRV200
2) WRVS4400N
3) RVS4000
4) RV016
5) RV042
6) RV082

and the most affordable is the WRV200 for around $75


can i do it site to site? as in i have to connect to vodafone to it and for it to be alive as long as someone from the company is connected to vodafone 3g. then vodafone goes through the gre tunnel to our network and the mobile internet modems get our ip.
can it be done this way?

actually i didnt test it using 3G connection, but since you are connecting to internet either 3G or wahtever then you get in as you are behind ADSL or leased line...etc


well, thing is that before now i had something similar using the windows 2003 server.
People were connecting to vodafone, then they were connecting to the windows 2003 server inside the network.
the work network currently has a domain controller which is a dhcp server too and a linux gw that just passes traffic. people were connecting to the domain controller to access the resources inside the network.
Now the people from vodafone offered us to create a tunnel (like a site-to-site vpn) from us to them (we have alot of 3g modems). so basically i have to create a GRE from a device here to their cisco vpn concentrator. then the modems will change apn to the vpn concentrator and so everything will be transparent for the end user. they will just connect to vodafone, but basically they will be inside our network using our internet connection.
So basically im asking what can i buy that is cheap and can do the above?

I have read through this thread and have not been able to make the VPN connection to my Win 2003 RRAS server work with my Linksys WRV200 router.  I have port 1723 forwarded to my RRAS server and PPTP passthrough enabled.  The firmware on my WRV200 has been updated to the latest version, v1.0.39.

Like others who have posted here, I am receiving an error message that the GRE 47 traffic is not being passed through the router.

Some posters have suggested that Symantec AV is creating this issue, so I have since changed to Sophos AV but this did not resolve the issue.

Can someone give me some direction as to what I should try next?
