Comunication between two server by firewall

[Claudio Plateroti]

Hello, everybody . I have to explain what’s the problem . The system is it : -          One server that send data by port 80 (the program is Perl, soap and xml) -          One firewall Linux between the two server -          And de other server that communicate by the firewall When the user send the information  the system displays this message :                         "500 can't connect 192.168.1.2:80 at /u1/faco" The question is : Why can’t connect the two server .   Thank you . Claudio
