>Description:
internal lan:
sis0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=48<VLAN_MTU,POLLING>
inet 10.3.226.2 netmask 0xffffff00 broadcast 10.3.226.255
ether 00:e0:18:27:06:41
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
external:
rl1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=48<VLAN_MTU,POLLING>
inet 10.109.226.3 netmask 0xfffffff8 broadcast 10.109.226.7
ether 00:02:44:a5:66:2e
media: Ethernet 10baseT/UTP
status: active
tunnel to other network on vtund on rl1 interface:
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1440
inet 10.3.2.226 --> 10.3.1.226 netmask 0xffffffff
Opened by PID 500
pipe:
${ipfw_cmd} pipe 25 config bw 4KByte/s
${ipfw_cmd} add 5025 pipe 25 tcp from any to any 25 via tun0 out
After reboot after some time packets large packets from boxes on port 25 from internal lan begin to disappear, but it seems that they aren't dropped.
>How-To-Repeat:
>Fix:
But it works fine enough with pipe like
${ipfw_cmd} add 5025 pipe 25 tcp from any to any 25 via sis0 in
