Hi,
I'm having a bit of a strange issue getting a single GRE tunnel to come up between my head office and a remote site. I'll be the first to admit, I'm quite new to new to setting up vpn's and the like so forgive me if I'm missing anything painfully obivious. The head office has around 14 different connections coming off all setup the same way with an IPSec VPN with a GRE tunnel to encrypt the data.

I can post more information if needed but I'm a tad stuck on this one, the routing I believe is correct as are the ACL's.
I would be most greatful for any help!
