Thanks to those who have replied to this issue. Despite their advice, the problem persists. I have a 4.3 FreeBSD box that has been running as a gateway for some time now. Recently, for some reason, it has now stopped passing data between nets. physical setup is: [ FreeBSD Box] LAN --> [dc0 <-----> rl0] --> DSL router/modem dc0 serves subnet 192.168.123 rl0 serves subnet 192.168.1 tcpdump confirms that tcp packets are arriving at the dc0 interface, but not leaving rl0. Access directly from the FBSD box to the Internet via rl0 works fine. All access from the LAN to FBSD box via dc0 works fine as well. packets just don't pass from dc0 to rl0. I haven't made any changes lately that I can think of. Any ideas greatly appreciated. Thanks. - - - - - - - - system info - - - - - - - - - - net.inet.ip.forwarding is set to "1" From /etc/rc.conf: ----------------------- defaultrouter="192.168.1.1" hostname="brightstar.ath.cx" #ifconfig_rl0="inet 192.168.1.2 netmask 255.255.255.252" ifconfig_rl0="DHCP" ifconfig_dc0="inet 192.168.123.8 netmask 255.255.255.0" inetd_enable="YES" kern_securelevel_enable="NO" sendmail_enable="YES" sshd_enable="YES" # -- sysinstall generated deltas -- # kern_securelevel="1" kern_securelevel_enable="NO" router_flags="-q" router="routed" router_enable="NO" gateway_enable="YES" named_enable="No" Netstat -r output : ----------------------- Routing tables Internet: Destination Gateway Flags Refs Use Netif default 192.168.1.1 UGSc 7 222 rl0 localhost localhost UH 1 21 lo0 192.168.1 link#2 UC 0 0 rl0 => 192.168.123 link#1 UC 0 0 dc0 => ifconfig output: ----------------- dc0: flags=8843 mtu 1500 inet 192.168.123.8 netmask 0xffffff00 broadcast 192.168.123.255 inet6 fe80::204:5aff:fe69:460c%dc0 prefixlen 64 scopeid 0x1 ether 00:04:5a:69:46:0c media: autoselect (100baseTX ) status: active supported media: autoselect 100baseTX 100baseTX 10baseT/UTP 10baseT/UTP none rl0: flags=8843 mtu 1500 inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255 inet6 fe80::250:bfff:fe3f:526d%rl0 prefixlen 64 scopeid 0x2 ether 00:50:bf:3f:52:6d media: autoselect (none) status: active supported media: autoselect 100baseTX 100baseTX 10baseT/UTP 10baseT/UTP 100baseTX God's Blessings, Gene To everything there is a season, and a time to every purpose under heaven.
