I found that /usr/sbin/gdmconfig was set to disallow TCP traffic from the Security tab. I've turned that off. 2. You mentioned that I should turn off ECN given that my default route is working alright. I believe it is working properly given that I can ping <a class="moz-txt-link-abbreviated" href="http://www.yahoo.com">www.yahoo.com</a>. I tried that using "echo 0 > /proc/sys/net/ipv4/tcp_ecn" and low and behold my telnet to port 80 works! I am now assuming that one of my ISPs routers is failing on the ECN. Is there an easy way to check which router is causing the failure?
