My network configuration is OK, ifconfig -au show : ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500 inet 200.20.30.1 --> 200.20.30.9 netmask 0xffffff00 >if you write to a public list like this, you need to supply as >much information as you can; ifconfig -au , /etc/rc.conf (relevant >lines), etc. I am using to serial link the program "pppd" of the FreeBSD 2.2.1 Distribution. The box have an interface ethernet, in the /etc/sysconfig: network_interfaces=" ed0 ppp0 lp0" ifconfig_ed0="inet 168.176.1.5 netmask 255.255.0.0" router="routed" router_flags=" -smt -P send_solicit rdisc_adv" gateway="YES" The topology : I have two box how routers, one run gated (A) and other run routed (B), conected with link ethernet, the router (A) anounnce OK to other neighbor EGP, all its paths. ------ EGP -------9 RIP 1-------- RIP | |----... --------| A |**************| B |-------- ------ ------- -------- 200.20.30 >> This link no interchange routing information. >> Need configuration especial in file /etc/gateways ?
