RV082 drops PPTP routes after a few minutes

Hi,

I'm using a RV082 as a VPN server for a medium sized (50-60 machines) office.

I can connect to it using the Mac OSX PPTP client, and it works quite well except that the connection seems to die after 4-5 minutes. Actually the VPN link stays up but suddenly I can't ping any hosts in the office and they can't ping me.

It seems that after a few minutes the RV082 is dropping one of the PPTP routes. When I connect there is two routes:

10.0.0.5 255.255.255.255 * 50 ppp200
10.0.0.251 255.255.255.255 * 0 ppp200

But after a while only the first one remains. (10.0.0.5 is the internal IP of the RV082, 10.0.0.251 is the VPN addr of my mac)

Anyone have a fix? I'm using firmware 1.1.6.3.

Really beginning to wish I'd not bought this machine...
 
I have noticed the same issues. That is why I just set up RRAS on an internal windows host and port forwarded pptp to it.

While it is more reliable, it is a shame I can't get the pptp server on the 082 to work since sometimes I have to reboot the windows box that hosts the RRAS.

wish I could help you out more.
 
Is your RV082 doing load balancing over 2 internet connections? If so this is probably the cause. pptp is flawless on my rv082 as long as it's not doing load balancing. If I turn on load balancing it drops packets as I guess it's trying to send some of them down the wrong wan link.
 
Thanks for the reply. I was indeed using the auto-balance mode, so I tried turning it off to see what happened. Unfortunately it made no difference, the route fell away after about 4 mins.

The rv082 really is a steaming pile of (*&#%#!!!

Might look at the m00nwall router next time round.
 
I also have no problems with the PPTP server. Of course I am running in DMZ mode, having only 1 WAN connection. I notice, however, that you are using Firmware 1.1.6.3 which is ancient relative to the current version of 1.1.6.14. Why not download this latest version from LinkSys and see if that helps your situation?

Hope it helps!
 
Try altering your MTU. Initially my quickvpn tunnel with my WRV54G kept bombing at 3 minutes. I adjusted the MTU and I've had solid performance for over 5 months now in both PPTP and Quickvpn:

As a suggestion, set your MTU either on the router or on the machine to 1350. This is a good stable packet size. Default for windows platforms is 1500.
