i known that the analog modem is a old technology, but in my enviroment i need it. I have a server connected to a network 192.168.0.0/24 and all the internet is routed throw 192.168.0.254 and in the 192.168.0.3 i was deploy a RAS server with an analog modem connected to ttyS0 (COM 1). I was configurated a mgetty with pppd and from my home i dial to the modem for the analog line and connect well ( 33 kbps ;) ).
The problem is that (in the client, my laptop) in Linux when the connection has 2:30 mins elapsed the modem hangup with error code 15, that the explanation is that the ppp process dont recieve a reply from the server, but in Windows the connection don't hangup.
The main problem is that when i connect, i make 'ping 8.8.8.8' and works!!! but if i intent connect with a browser to www.google.com don't work, even i test connect with ssh with my server (without firewall), try and try, but never connect. Using wireshark i see that the packet is send but not return a response from the server.
In Windows I see that the connection has many errors in the input way. My configuration files are this
