I am using RV042 Dual band Routers in my multiple site, when i am trying to connect all router through ip Sec tunnel only 5 tunnel is working rest others are disconnect, some one help me.
I have logged a case in Cisco small business support but not getting valid answer, they told that 4 ports (50,51,500,4500) is block by ISP so it creates problem but if ports block is problem then why some tunnels is working fine.
