Market and Gmail won't connect via wifi, but will over 2G/3G..Other internet works

We have a vibrant and a captivate.. When connected via wifi at home, the market and gmail will not connect, but both phones access the internet just fine otherwise.. They connect fine to the market and gmail using 2G or 3G, or other wifi networks..
Can anyone let me know what settings I might adjust on the router to allow connections to gmail or the market on these phones?
