Hi, I'm quite new to FreeBSD and have got problems with getting an sppp connection running. After I've been trieing for days, it seems to me that it is not directly an ISDN problem, but an sppp, routing or firewall problem. Hardware: 486-133, 80 MB RAM, Teles S0/16.3 card Software: FreeBSD 4.0, i4b 0.90 Configuration: See below. I configured my sppp according to the example in Hellmuth's nice "The care and feeling...". BTW, the GZIPped PostScript version at "http://www.freebsd-support.de/i4b/" seems to be defective. Syntoms: ----------------------------- bash-2.03# ping 191.1.1.5 PING 191.1.1.5 (191.1.1.5): 56 data bytes ^C --- 191.1.1.5 ping statistics --- 4 packets transmitted, 0 packets received, 100% packet loss bash-2.03# telnet 191.1.1.5 Trying 191.1.1.5... telnet: connect to address 191.1.1.5: Can't assign requested address telnet: Unable to connect to remote host bash-2.03# -------------------------------- The remote address is correct, the same thing works perfectly from my OS/2 machine (also a BSD TCP/IP stack 8-)) using ISDNPM. Repeating does not make any difference. During such tries it seems that an ISDN connection is established, but no data is transmitted via the interface: -------------- bash-2.03# ifconfig isp0 isp0: flags=a015<UP,DEBUG,POINTOPOINT,LINK1,MULTICAST> mtu 1500 inet6 fe80::200:1cff:fed7:6060%isp0 prefixlen 64 scopeid 0xd inet 0.0.0.0 --> 0.0.0.1 netmask 0xffffffff bash-2.03# telnet 191.1.1.5 Trying 191.1.1.5... telnet: connect to address 191.1.1.5: Can't assign requested address telnet: Unable to connect to remote host bash-2.03# ifconfig isp0 isp0: flags=a055<UP,DEBUG,POINTOPOINT,RUNNING,LINK1,MULTICAST> mtu 1500 inet6 fe80::200:1cff:fed7:6060%isp0 prefixlen 64 scopeid 0xd inet 192.168.173.64 --> 0.0.0.1 netmask 0xffffffff -------------- Any ideas?
