That would depend on the location of your rules files.  If both of your
snort-eth?.conf files point to the same rules directory, yes.  

If you have RULE_PATH defined the same in both files, they are sharing
the same rules.  This would also apply for SO_RULE_PATH and
PREPROC_RULE_PATH, if you have them defined.

Dear all, I have a Snort 2.9 box with two sniffing interfaces:

1) eth1 sniff DMZ traffic --> in snort.conf HOME_NET = 172.18.10.0/24
2) eth2 sniff LAN traffic --> in snort.conf HOME_NET = 10.10.0.0/16

Is it better to have two different snort.conf files, for example:

snort-eth1.conf
snort-eth2.conf

and run two snort instanes like these:

snort -D -u snort -g snort -c /snort/etc/snort-eth1.conf -i eth1
snort -D -u snort -g snort -c /snort/etc/snort-eth2.conf -i eth2

In this case, what happen if I download rules with oinkmaster, will
they apply on both snort-eth1.conf and snort-eth2.conf files ???

Or what is the best way to do I need ???

Really thanks,

JeLo
