Hello, We had a network outage at our campus (severe thunderstorm). Under a small lan, I had a FreeBSD NAT box (IPFILTER + IPNAT) connecting a private network to the outside (The outside IP address was 132.254.97.16, and an alias of 132.254.97.17). The private network was numbered 192.168.0.0/24. I say was because when the internet connection came back, I couldn't ping my router. Very strange. I called the IT support department at the campus, and they brought a win2k box to hook up. It saw our router (132.254.103.250) on the first try. When I went back to the FreeBSD box, it failed, again and again. I've recompiled my kernel, I also recompiled the generic kernel (plus "options ipfilter") but to no avail. Still, I cannot see the router. Now here comes the punch. There is also a private network running on the inside of the campus (10.25.0.0/16). If the FreeBSD box is configured to get an IP address from DHCP, it gets a private IP address (10.25.128.150) and it works just fine. NAT works great, along with everything. If I put the following lines in my /etc/rc.conf, it wont work, but if I use the same data on a win2k machine, it works perfectly: ifconfig_xl0="inet 132.254.97.16 netmask 255.255.248.0" ifconfig_xl0_alias0="inet 132.254.97.17 netmask 255.255.255.255" defaultrouter="132.254.103.250" With that, when I try to ping 132.254.103.250, I get the error "Hos is down". Doing the same in windoze works perfectly. I hate that, and we need to get this FBSD box working right now. Thanks for any help, Mario Doria _________________________________________________________ Do You Yahoo!?
