Yes it' a real IP.

I've changed it to the config file below. But it still won't work. My ISP is vergin media. Can someone please tell me what I am doing wrong?

Hello,

Don't use any any in the access list, use the actual IP address space of the LAN. Also, post the full configuration of the router, not just snippets...

[kmykoo]

What do you mean the actual IP address space of the LAN?

[Georg Pauwen]

Hello,

the IP address in your original post looked like a public IP address, that is why I was asking. Either way, your access list still doesn't look correct. Post the full configuration of your router, not just snippets...
