Hi Cisco family,
I've been working on this config for over month now and its driving me insane. After lot of tweaking I've got this config to work with my BT infinty 2 Internet connection which is a UK based VDSL2. NAT overload works perfectly for all my hosts. Tricky part is i can't seem port forward my web server which is assigned 10.20.20.199 and is VLAN20 on my Layer 3 switch(Please see the network diagram).What am I doing wrong ? Port forwarding works with supplied BT router (BT homehub 5) so I think it is safe to assume its not ISP side. Thanks for taking interest in this matter and for contributing. Appreciate your help.
