This is a multi-part message in MIME format. ------=_NextPart_000_0016_01C10FB4.F89615C0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Dear FreeBSD ubergeeks, Please help me with this, I've banged my head against the wall until my = forehead has taken on a flat bricklike appearance trying to figure out = how to fix my problem. I can't get my machine to respond to any = requests to port 25. It's not closed, I just get no response, as if the = port does not even exist. At first I had sendmail listening on 25, and = I thought the problem was there, so I installed qmail (and am much = happier with it), with the exact same results. Any request to port 25 = outside of my happy little class C is ignored. On the other hand, from = within my LAN, there is no problem whatsoever. Upon telneting into my = box on port 25, I'm greeted with "220 lowroad.dhs.org ESMTP", and mail = sent comes in fine. Here is a traceroute from an external network: traceroute -p 25 lowroad.dhs.org trying to get source for lowroad.dhs.org source should be 209.130.129.238 traceroute to lowroad.dhs.org (24.93.15.166) from 209.130.129.238 = (209.130.129.238), 30 hops max outgoing MTU =3D 1500 1 fe5-0-0.ar1.ROC.globalcenter.net (209.130.129.193) 2 ms 1 ms 1 ms 2 fe4-1-0-100M.br2.ROC.gblx.net (209.130.187.130) 2 ms 2 ms 1 ms 3 pos2-2-155M.cr2.ROC1.gblx.net (206.132.119.205) 2 ms 2 ms 2 ms 4 pos1-0-622M.cr1.WDC2.gblx.net (208.178.174.118) 20 ms 19 ms 19 ms 5 so1-1-0-622M.br1.WDC2.gblx.net (208.178.174.54) 20 ms 21 ms 20 ms 6 att.so2-1-0-622M.br1.WDC1.gblx.net (208.51.74.182) 21 ms 22 ms 23 = ms 7 gbr3-p50.wswdc.ip.att.net (12.123.9.50) 21 ms 20 ms 19 ms 8 gbr3-p80.n54ny.ip.att.net (12.122.2.165) 26 ms 26 ms 26 ms 9 gbr6-p60.n54ny.ip.att.net (12.122.5.113) 26 ms 25 ms 25 ms 10 gar2-p370.n54ny.ip.att.net (12.123.1.205) 26 ms 26 ms 26 ms 11 12.124.179.34 (12.124.179.34) 34 ms 34 ms 34 ms 12 syr-24-92-224-36.nyroc.rr.com (24.92.224.36) 41 ms 41 ms 41 ms 13 brighton-mcr2.nyroc.rr.com (24.93.0.170) 43 ms 45 ms 42 ms 14 brighton-mcr2.nyroc.rr.com (24.93.0.170) 43 ms 42 ms 43 ms 15 * roc-24-93-15-166.rochester.rr.com (24.93.15.166) 93 ms 56 ms (I want that little *SPLAT to go away) And now here is one to a Windoze machine on the same cable modem: traceroute -p 25 prometheus.lowroad.dhs.org trying to get source for prometheus.lowroad.dhs.org source should be 209.130.129.238 traceroute to prometheus.lowroad.dhs.org (24.93.15.103) from = 209.130.129.238 (209.130.129.238), 30 hops max outgoing MTU =3D 1500 1 fe5-0-0.ar1.ROC.globalcenter.net (209.130.129.193) 2 ms 1 ms 1 ms 2 fe4-1-0-100M.br2.ROC.gblx.net (209.130.187.130) 2 ms 1 ms 1 ms 3 pos2-2-155M.cr2.ROC1.gblx.net (206.132.119.205) 2 ms 2 ms 2 ms 4 pos1-0-622M.cr1.WDC2.gblx.net (208.178.174.118) 20 ms 19 ms 19 ms 5 so1-1-0-622M.br1.WDC2.gblx.net (208.178.174.54) 19 ms 19 ms 19 ms 6 att.so2-1-0-622M.br1.WDC1.gblx.net (208.51.74.182) 19 ms 20 ms 19 = ms 7 gbr3-p50.wswdc.ip.att.net (12.123.9.50) 19 ms 19 ms 19 ms 8 gbr3-p80.n54ny.ip.att.net (12.122.2.165) 26 ms 26 ms 26 ms 9 gbr5-p60.n54ny.ip.att.net (12.122.5.105) 26 ms 27 ms 26 ms 10 gar2-p360.n54ny.ip.att.net (12.123.1.201) 27 ms 29 ms 26 ms 11 12.124.179.34 (12.124.179.34) 34 ms 34 ms 34 ms 12 syr-24-92-224-36.nyroc.rr.com (24.92.224.36) 44 ms 44 ms 41 ms 13 brighton-mcr2.nyroc.rr.com (24.93.0.170) 42 ms 43 ms 43 ms 14 brighton-mcr2.nyroc.rr.com (24.93.0.170) 43 ms 43 ms 43 ms 15 roc-24-93-15-103.rochester.rr.com (24.93.15.103) 49 ms 58 ms 85 = ms I can't figure it out.
