. . . .|Could these services be blocked by my ISP @Home? . . . .|Is there a way to tell? I know for a fact that @home does block port 80 access and port 25 [my friend ran it for like 6 months and they cut him off] I'm gonna guess they will soon block all system ports [ <1024] you can try opening the firewall wide open and double checking, you can try running traceroute and see where it dies. you can also run ssh on a different port [above 1024 would be good] My traceroute shows that @home is killing it, as far as I understand: 10 c1-pos3-0.clevoh1.home.net (24.7.64.174) 45.748 ms 45.729 ms 59.189 ms 11 c1-pos2-0.iplsin1.home.net (24.7.65.245) 91.956 ms 55.04 ms 65.003 ms 12 c1-pos2-0.lsvlky1.home.net (24.7.69.10) 75.899 ms 55.692 ms 57.756 ms 13 bb1-se1-0.lxintn1.ky.home.net (24.7.73.78) 60.372 ms 57.324 ms 58.124 ms 14 ubr1.lxintn1.ky.home.net (24.5.116.25) 62.913 ms 61.305 ms 58.739 ms 15 * * * 16 * It never gets to you, which usually means a firewall is in place between me and you.
