Urgent help

[mwwg]

i have cisco 1841 in main office connected by IPsec tunnel to a branch office with cisco 877, before installing the c877 the ipsec tunnel was working using a 3rd party router now its up but usless as the c877 firewall drops most connections & i can't understand why?

my question is what are the default setting which come with c877 firewall? & how to set it to get communication between the child domain in the branch office & the parnet domain in main office? esepcially we have exchange & terminal server in both sides, also this is preventing users with cisco VPN client as they could connect but their RDP request times out. thanks for any suggestions
