    Comtrend Comtrend CT-5071T: Port Forwarding

    I was trying to do a Port Forward on a Comtrend Router Model# WR-5882 and was unable to find any information as far as screenshots and step by step processes. I have looked at Portforward.com and in the forums. If you could please add any information on
    this model or point me in the right direction to find it, that would be greatly appreciated!

    Hey there Jason!

    [quote user="JasonXmurder"]

    Modem brand & model number: Comtrend ADSL2+ (CT5621T)

    Router brand & model number: Linksys (WRT54G2 V1)

    [/quote] You have two network devices doing NAT on your local network (not good), if not your Comtrend (CT5621T) is already setup in bridge mode that is. Have you configure your Comtrend wireless gateway in bridge mode?

    Nat Type Strict

    Greetings BladeRaxor1!

    HaglePer is correct!

    The Comtrend CT-5372 has router built-in to this device and since you connect an additional router to this device, (Asus RT-N56u) your connection will be NAT'd twice for traffic forwarded to your Xbox. This scenario all make sense with a symmetric NAT
    behavior/strict NAT.

    Could you therefore verify if your Comtrend CT-5372 is operating in bridge mode.

    Thank you!
