We are trying to make VPN connections from a branch office through a WRT54GS router.  The connections fail, as protocol 47 (GRE) is apparently not supported on this model.Has anyone else run into this?  Any advice?
Kudos!

Hi
:smileyhappy:
When you have PPTP option in the router,that mean you can use tunneling point to point tunneling protocol through the router.
You have section VPN,configure that section with 3 ticks(IPSec,PPTP,L2TP),then the clients who dialin the router will must have in Connection Properties " Type of VPN" - Automatic(autodetect what protocol want the dialin point->router  - IPSec,L2TP or PPTP ).It should work.
 
Good Luck!!!!!!!

Hi. I have a similar problem here :smileysurprised:(
 
I just installed a WRT54G with basic configuration in my office and would like to connect a station with XP (10.0.0.1) to another network (other XP with PPTP configured) using PPTP.
 
All VPN protocols are checked/enable (PPTP, L2TP,etc).
 
I create a rule in Applications & Gaming/Port Range Forward page with
 
pptp1   1723   1723   10.0.0.1     enable ticked
pptp2       47       47   10.0.0.1      enable ticked
 
When I try a connection a box open saying that´s checking my username/password and I receive a time-out disconection.
 
I try to open all ports and put this machine in a DMZ mode, and the same problems occours.
 
I put this computer connect directly to my adsl modem and PPTP works fine!
 
What I need to do in this case?!
 
Thanks in advance.

Hi
 
I use another topology for this situation.
 
I just put my ADSL modem in bridge mode and let Linksys to work just a unique router in the network.
 
Other way is change the firmware ... but this operation have risks.
 
My best regards. and good luck.
Kudos!
