Tunnel Down after some period of time

[vvelasco]

Hi all,

I configured 2 CISCO 837 using SDM,

Type of VPN : Site to Site, with share key.

Both sides with ADSL and Fixed IP (real ip).

I sucessfuly up with "TEST TUNNEL" but the VPN didn't up if I shutdown any router.

After some time the tunnel goes down and I don't know how to keep the tunnel up. I tried keepalive parameters with no good news.

Any suggestion?

The tunnel should come up automatically when traffic is sent across it.

Failing that, take a look at this tool to generate site to site configs:

After some testing I found that it come up automatically.

Nice link, I'll test.
