[Connection Sharing] Ubuntu 12.04 as a gateway/router problems
I am trying to set up a Ubuntu 12.04 box to act as a router for my other computers. I have tried several procedures that I found on the net. The best I can do is the following procedure from »www.gentoo.org/doc/en/home-router-howto.xml
I have no problems accessing the net from the Ubuntu computer. However the other computers can only access certain web sites. They can get to google.com but not dslreports.com. They start to load ebay.com but stall. I am guessing that there are items on some websites that point to other web addresses and these are the cause of the pages not loading.
I uncommented most of the ipv4 items in sysctl.conf and that resulted in the same problem.
Next I changed the mtu on the other computer to 1492 (it was 1500) and presto it worked. Now I have to go back to sysctl.conf and comment out things I do not need, if I can figure out which are needed and which are not. ob Thank you Bob
