In the central US (Kansas) they are filtering more than just port 25 outbound. After a few hours on the phone with level 2, whatever, support.. I was told that "We do not block any ports on your connection." To my dismay, and acute disbelief (with evidence in hand) I questioned the all mighty guru's once again: "Why are you blocking my outbound traffic?" They replied: "We do not block any ports on your connection! You apparently don't know what you are talking about or have a problem with your computer!" Ha, after I paused in disbelief I had discovered that there was some truth to what he said. I had neglected to bring myself up to the 'politically correct' terms of today. You see, since about 1979, my thinking was (and still is) that anytime data is being intentionally prohibited either in or out of the interface; then to me it is being 'blocked' - for whatever reason. So I asked the engineer, "Ok then, why can't I send my email to my corporate servers without having to go through your mail servers?" His reply? - "Well that is because we filter many ports both inbound and outbound." Today, I'm educated once again: No it is not being blocked, it is being 'filtered'. Ha, filtered. Hehe.. I could of saved myself about 3 hours of life had I kept my wits up and just remembered to think outside the box. 'filtered'. Ok then it's filtered. How do have the filters removed? His reply was to have me go to there email abuse web page, select port 25 opt out, fill in the comment box and click submit. Well I did that.. Cgi error - 404 page not found. Ok, yet another 1 hour call to tech support. Tech support had to actually fill out my information for me and try try try until their own form would submit. My next 'outside the box' question was: Ok how do I have other ports 'not filtered' hehe.. Like ports 5177, 5178, 8181, 8383, etc etc? He said he didn't know if 'they' would do that. Trying to make his work easier I finally just asked if they would remove all 'filters'. Worth mentioning is that they do, here anyway, use IPSwitch IM (on the lan probably) so the tech understood my frustrations about not having 5177/5178 open. So, I'm on day 2 awaiting the release of the 'filters'. Tomorrow I cancel my xDSL connection and press on with COX. I just find it hard to believe that a company that big would have such lame methods inplace, to BLOCK their customers use of the internet, with little to no way of selectively removing 'filters' imposed upon them. I would hope that come to a firm conclusion and realize that not everyone that uses there service just surfs the internet. ~Rick _____________________________________________________________________ Virus Scanned and Filtered by - http://www.FamHost.com E-Mail System.
