Call of Duty 4 - High Ping

[bluetech]

For some reason, when a friend connects to my game for BF2 or Crysis, avg ping is 30 - 40 ms. On COD4 v1.4, this is now 130 - 150 ms causing lag on the server. Any ideas why this could be?

Using hardware firewall with COD4 ports forwarded. No AV or Firewall installed.

Thanks

Is it a US server?

I get a low ping on some servers, and high on others. Much like ^

My game is hosted in the UK, along with the person reying to connect to my game. The odd thing is that Crysis and BF2, pings are as they should be from him. But COD 4 is really high and unplayable.
