I've been stuck on this for a while, and I can't seem to do it. I have a Linksys router, and whenever I try to forward the ports, it always has the preset 192.168.1.XXX set it, and I can only change the last 3 digits to my IP address. The only problem is, my Mac can only access the internet when it's IP is a 10.10.10 address. If it's not, i have to renew the DHCP Lease before I get a connection. What to do?? Thanks!
