IP setup looks like this. root@snort:~# ifconfig eth0 Link encap:Ethernet HWaddr 08:00:27:fd:b5:c4 inet addr:*172.28.61.104* Bcast:172.28.61.127 Mask: *255.255.255.128* inet6 addr: fe80::a00:27ff:fefd:b5c4/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:472894 errors:5 dropped:15 overruns:0 frame:0 TX packets:15266 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:129789824 (123.7 MiB) TX bytes:2332609 (2.2 MiB) Interrupt:10 Base address:0xd020 eth1 Link encap:Ethernet HWaddr 08:00:27:97:66:ff inet addr:*192.168.123.1* Bcast:192.168.123.255 Mask: *255.255.255.0* inet6 addr: fe80::a00:27ff:fe97:66ff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:14 errors:0 dropped:0 overruns:0 frame:0 TX packets:438796 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:962 (962.0 B) TX bytes:123829936 (118.0 MiB) Interrupt:9 Base address:0xd240 The eth0 interface is the outside and eth1 is inside. I'm starting snort with this command. snort --daq afpacket -i eth0:eth1 --daq-mode inline -c /etc/snort/snort.conf But I still cannot ping an inside host from the outside. I can ping between the snort device and inside/ouside hosts. If I ping an inside host from the outside, tcpdump shows the icmp echo request arriving but no reply. Inside host ip is 192.168.123.2. Can anyone recommend some other troubleshooting steps or suggest where I may have left anything out of the setup?
