Once I connect both the interface (eth0 and eth5) to my network. I can't ping to my router (connect to eth0) or ping to my other IP addresses (connect to eth5). I check around and found out some messages pops up in /var/log/syslog file as below: - Jan 2 10:44:22 fw01 kernel: ipt_tcpmss_target: bad length (64 bytes) Jan 2 10:44:32 fw01 last message repeated 11 times Jan 2 12:27:08 fw01 kernel: Neighbour table overflow. Jan 2 12:27:11 fw01 last message repeated 9 times Jan 2 12:27:13 fw01 kernel: NET: 10 messages suppressed. Jan 2 12:27:13 fw01 kernel: Neighbour table overflow. Jan 2 12:27:18 fw01 kernel: NET: 27 messages suppressed. Jan 2 12:27:18 fw01 kernel: Neighbour table overflow. Once I disconnect the cable from the eth5 interface, I can ping to my router. I try to reconnect the cable back to the eth5 interface and run a ping to my router. As the result, I can't ping the router and the similar messages pops up in the /var/log/syslog file. How can I resolve this issue? Regards, ro0ot
