These are certainly noobs question so any answer is appreciated. Is there any relation between proxy type and port? Why port like 3127,3128,3129 are not accepted by CL although they are very fast ? I can post occasionally to CL using elite proxy. Only port 80 is accepted by CL others such as 8080 or 9090 generally fails. This incidences make me inquisitive about port. Any help about getting anonymous , elite fresh and working proxy for UK. I need then to post on Gumtree.
