Re: [PLUG] Verizon port blocking?

["Brent Saner" <brent.saner@gmail.com>]

i'll try. :)
i don't know the specifics but i do know that 80 inbound (web) and 25 outbound (mail) are definitely blocked, as these are the only two verizon explicitly states. others i'd strongly imagine are blocked are indeed 21 (as well as 20) (ftp), 23 (telnet), 22 (ssh), 3389 (windows rdp), 69 (tftp), 113 (ident..what you'd find in IRC ident. systems), and a lot of others.

i do know that compared to comcast, for instance, there have been stories of substantially more blocked ports with verizon fios.

can you elaborate on this?  my untested (still need to setup that ISP
auditing box) understanding was that inbound 80 was blocked and
outbound 21 (except for their smtp domain), but that's it.  basically,
don't run a webserver or a mailserver, unless you're willing to pay
dyndns or no-ip to do port-mapping for you, or use non-standard ports.
 (word up about the 8080 being open though.)
