Trouble setting up cctv mobile connection on port 80
I have recently connected a Nightwatcher CCTV system I am unable to complete the system because Nightwatcher tells me th Virgin media blocks port 80 which this system uses to connect to. So I am unable to set up 4g mobile acces because of this port being closed. I rang Virgin media it was going to cost me £60 to talk to a third party to resolve this problem I was disgusted have never had to pay before. I have seen on some of these forums about port forwarding but I have never done this before and only have little computer tech knowledge. Has anyone got any suggestions of how to do this or get the mobile 4g working without doing this any instructions or videos would help.
