Connection timeouts with mobile vpn users

We just setup a colocation and all connections from our main site to colocation site seem fine.  When remote user connects I start getting timeouts.  Here is the setup.
At main office we have a Watchguard router, at colocation is a Fortigate router.  The gateway and tunnels are setup for site to site between the 2 and it works.
At the main site on the DC, I have sites and services configured accordingly.  The main site subnet is 192.168.0.0/24 and the remote site is 192.168.10.0/24.  I moved one of the DC's into the server portion of the remote site.  When I connect using the WatchGuard VPN client I get assigned an address on the 192.168.113.0/24 subnet.  I can see all servers and access all machines on the .0.0/24 subnet without issue, when I try and hit the servers on the 10.0/24 subnet I get a few replies and then couple timeouts.  If I try a continuous ping I may get up to 12 replies before getting 2-3 timeouts and then replies again.  Also, if I run a continuous ping from my machine at the office (on the 0.0/24 subnet) I get all replies but will start getting some timeouts if someone connects via the WatchGuard VPN client.  
I am hoping I am just missing a step as this is becoming frustrating.
If anyone can provide any insight it would be greatly appreciated.

You may need to turn NAT traversal ON. Also a site-to-site tunnel will use MAIN Mode. Mobile users use AGGRESIVE Mode. Make sure the mode is correctly set.

John,  We switched to Aggressive mode and latency still existed.  Turns out they had something wrong on the Fortigate tunnel side.  Once they removed the Tunnel and reconfigured in a different manner, I no longer received any packet loss when remote.'
Thank you for the suggestion.
