the situation is this, I have a firewall (fbsd of course) , with many aliases in the internal LAN interface
and tcpdump dont see the packages
My config:
the main LAN is 154.2.0.0/16
and when I do this:
gives me nothing, I try with diferent filter, dst and src, boot ways...
In another interface with one ip it works fine
I read that
maybe works..but is not supported in this version of tcpdump or in FreeBSD
also I try
for example, and give incorrect interface,maybe it only works on linux
and tcpdump dont see the packages
My config:
Code:
INT em1
inet 154.2.6.xxx netmask 0xffff0000 broadcast 154.2.255.255
inet 10.1.101.xxx netmask 0xffffff00 broadcast 10.1.101.255
inet 10.1.60.xxx netmask 0xffffff00 broadcast 10.1.60.255

inet 154.2.6.xxx netmask 0xffffffff broadcast 154.2.6.155 < (jail with DNS server)
the main LAN is 154.2.0.0/16
and when I do this:
Code:
tcpdump -l -nn -vv net 154.2.0.0/16 and port 4433
In another interface with one ip it works fine
I read that
Code:
tcpdump -i any
also I try
Code:
tcpdump -i em1:1
