Port Forwarding not working

We recently upgraded to Xfi gigabit internet. Before we upgraded I had no problems forwarding ports through 10.0.0.1, now i am unable to through Xfi. Ive tried contacting customer support and they just advanced me. Ive searched the internet for hours and tried everything i can find. disabling advanced security, disabling my ipv6 on my computer, nothing seems to work. I need to forward 7777-7780 and 27015-27020 for my ark server in order for me and my friends to connect to it. Like I said ive had 0 problems portforwarding before upgrading and only when we upgraded did i have a problem.
