Hi,
I have a branch router in a different country with IPSEC VPN tunnels set. Recently there are intermittent latency issues due to Network Congession experienced by the ISP in the remote country.
My st0 is set with default MTU size. Would I see any improvement if I change MTU size to 1500 for the st0 interface only for the remote router? Do I need to change TCP MTU size too?
