Just a quick question I am working on a project in Poland and have got all my UC520 kit with me. I use a Polish ISP Netia.Is it possible somehow to mask my WAN Ip address to match my UK ISP BT broadband IP address.The reason for asking is that I cannot access any of my Sky online services and other UK related websites.If this can be done without going through a proxy server based in the UK and can be done by simple CLI code this would stop the heart ache.
There is not a way to mask or spoof your ip address on the WAN interface. The only real way to get around this is using MPLS. MPLS uses a "layer 2.5" marking just after the mac address to identify its route through the isp cloud. This would keep the isp from looking at the layer 3 address. If you had an MPLS tunnel back to the "home" network then you could consider it as a work around for your situation. The only other way is to use a proxy server.
