Im using a cisco 877W router(ip 192.168.0.1), which is on the 192.168.0.0 ip range, and I have a dvr server which is on 192.168.0.10. I need this server to be available to the internet, so i need to forward certain ports onto that IP. My question is do I need to setup an access list as well as creating a ip nat inside source static rule.
I also have another subnet on 10.0.5.0, and a router/dhcp server at 10.0.5.20/192.168.0.2, and need to setup the Cisco 877W as a VPN server. If VPN server traffic terminates on the CISCO, do I just need to program a route to 10.0.5.0 via 192.168.0.2.
