Hi Techies,

I am using mikroitk server hotspot and recently we given a new connection to the client he was using cisco router to connect the server via ipsec tunneling but unfortunatey he is getting the following errors in cisco console. we given global ip (175.XXX.XX.77) to the customer even it also not works and tried to open the ports of 500 & 4500 but no use.
