Hi, all! Have a problem - I use Net::SMPP(v.1.04) perl module from CPAN.org for connecting to remote SMPP service server (SMPP version 0x34). My software (Perl script) working OK on SMPP service provider's server, but don't working on my server - as we se in all accessible logs - it's connecting to remote server then stopping and do nothing. My server firewall succefully permit this connections and "telnet" to remote host is OK. As service provider appologize his firewall also permit connections from my IP address. Who seen trouble like this - please help. Thank's for your attention, Regards, Alex.
