Can a site-to-site IPSec VPN co-exist with a remote-access L2TP VPN?

The subject pretty much says it all - can a site-to-site IPSec VPN co-exist with a remote-access L2TP VPN?

I have two sites linked with a site-to-site IPSec VPN, and I can't afford for it to go down as I'm moving a lot of data between them at the moment.

I am therefore hesitant to test setting up a L2TP VPN for remote access. I'm aware that setting up L2TP for remote access involves dropping into the command-line, or playing with the Config Tree.

I can't see why it wouldn't work, but I'm not 100% sure. Can anyone confirm for me that they can co-exist happily?

Thanks,

Kai
