RV042 VPN Timeout Problem

[ACadmalmere]

Hi,

I have trouble to remove the timeout created by the RV042 VPN Router.

If I configure the Cisco VPN, the timeout occur every 30min.

If I configure SBS 2003 VPN, the timeout occur every 30min.

I have enabled/disabled the following:

1. PING on WAN enabled

2. SPI disabled

I have upgraded the Firmware to the latest version.

The exact problem:

VPN connection doesn't drop, only the communication with the external network.

This happens only when the VPN is idle for 30min.

When I adjusted the Cisco TCP Timeout from 30min. to 3 or 8 hours, the connection with the external network will drop after 18min. of idle time.

If I change it back to the default of 30min. the connection will drop after 30min. of idle time.

Question:

How can I make sure that the connection with the external network will be active for at least 3 hours?

I know I can setup a Batchscript with a ping, for keeping the connection alive, but I don't want to use workarounds.

Good morning.

Thanks for using our forum.

Hi Jan my name is Johnnatan and I am part of the Small business Support community.

You can try a factory reset in order to resolve you problem (always make a backup of you r configuration), and restart you VPN configuration, if the problem persists, check your MTU packets size (recomended 1500). You can also Go configure your VPN tunnel and disable the “perfect forward secrecy ” and enable “Keep-Alive”, you can do this in the step 12^th and 13^th of the following document.

Thanks,

The "Factory Defaults", I didn't tried it yet.

I will do this a.s.a.p.

The MTU was part of my first Troubleshoot, but good that you mention it.

The VPN "Keep Alive" was turned on, when I used the Cisco build-in VPN.

I will try the "Factory Defaults" as last resort.

If it doesn't solve the problem, the customer have to deal with the 30min. idle timeout or change router.
