I was trying to enable Ipsec tunneling in one customer place.the Network setup is like this.
the customer is using cisco 1761 Router in both which has 2 serial interfaces &ve connected the same using a leased line connectivity .this line is using for failover meanwhile we have two installed a Micro Red modem in both end to establish a wireless connectivity with gives 6 mbps output (this link is working as primary link).but this modem does nt have a V.35 interfce ,only Rj45 interface is available.so I terminated the same to a Dlink unamaged switch ,ethernet interface of the router also teminated to the same switch & Gateway of all the internal clients is pointing to routers ethernet interface.
Here the problem is like this, as financial organisation ,the client needs enable Ipsec tunneling in wireless link also even though it have an in built security mechanisum .So after enabling the ipsec tunneling in router the Bandwidth goes down to 1 mbps.
Thsi time Cpu utilization goes upto 90% also.
So let me please know is it problem of interface termination ? or router load issue .Please give a solution for the same ASAP
Thanks & regards
