Hi Vitaliy,

One way could be to install arping from /ports/net/arping
and see if you can reach the NIC on the border router
from the LAN zone.

Cheers,

  Hi.
Since I setuped Jail for www stuff in server  there are network problems. 
Router has 3 NIC's in bridge with aliases.

cloned_interfaces="bridge0"
ifconfig_bridge0="addm rl1 addm rl2 addm rl3 up"
ifconfig_rl1="up -wol"
ifconfig_rl2="up -wol"
ifconfig_rl3="up -wol"
ifconfig_bridge0_alias0="inet 10.11.1.1 netmask 255.255.255.0"
ifconfig_bridge0_alias1="inet 10.12.1.1 netmask 255.255.255.0"
ifconfig_bridge0_alias2="inet 10.13.1.1 netmask 255.255.255.0"
ifconfig_bridge0_alias3="inet 10.14.1.1 netmask 255.255.255.192"
ifconfig_bridge0_alias4="inet 10.15.1.1 netmask 255.255.255.0"

Also I use PF for filtering traffic. There are a lot of rules. In two words: it 
is unable to reach any host in LAN and also any IP addresses on router, allowed 
access to Internet only. In other words Jail in original DMZ zone with IP 
10.15.1.1.

In random time (about one incident per-(2|3)days) the strange situations is 
occur: I am unable to ping/ftp/http from jail or from LAN any host in Internet. 
From/to router - it's ok. Restarting PF and jail seems to have no effect, only 
router's reboot.

 From pftop I see traffic, coming from jail or LAN but in the other way - no.

Anybody can give me some help in debugging this situation and figure out the 
problem?
