Hi Helge,
I've configured my linux pc as a isdn-dialin-server and the dialin is working just fine except that as long as the firewall is activated I can't ping the pc which dialed in and pinging from the other way round isn't possible, too - nor is any other kind of network communication (SSH, HTTP, etc.). The firewall seems to block the dialed in computer (ippp0). Which settings do I have to set up that when a other PC dials in it can access at least my linux pc over SSH (Port 22) and HTTP (80).
The easiest way would be to treat your dialup connection as an external connection as well. Thus, the only thing you have to do is to edit /etc/sysconfig/SuSefirewall2 and change FW_DEV_WORLD="ppp0 ippp0" and FW_SERVICES_EXTERNAL_TCP="ssh www". However, this would also open ssh and http connections over the internet. Therefore I would not change FW_SERVICES_EXTERNAL_TCP but add the IP/net of the computer you're dialing in to FW_TRUSTED_NETS and change FW_SERVICES_TRUSTED_TCP="ssh www" to allow those two protocols only from your dialing in computer but not from the internet. yours Jörn ------------------------------------------------------------ Jörn Ott Telefon: (0 22 24) 94 08 - 73 EDV Service & Beratung Telefax: (0 22 24) 94 08 -74 Lohfelder Str. 33 E-Mail: mailto:white@ott-service.de 53604 Bad Honnef WWW: http://www.ott-service.de/
