[c-nsp] Hub-Spoke IPSEC tunnels

[Mounir Mohamed]

Dear All,

I have centeral Firewall (PIX535) in HQ peering via IPSEC tunnles with other
3 branches, all branches using Cisco 1700 with IOS feature set currently
there is IPSEC tunnel between each branch and HQ FW, i need to configure the
centeral FW to doing routing between all branches, so if branch x need to
communicate with branch y it should establish it's IPSEC with HQ, then the
HQ using the incoming traffic to initiate IPSEC tunnel with y (if idel) then
routed the traffic between both branches.

Mainly i need to do Hub-Spoke IPSEC tunnels due to lack of hardware in the
remote branches routers.
Is that allowed, If yes kindly advice.
