ipfw2 in 4.7 == incorrect stats ?

2003-03-03 Thread Josh Brooks
Hello, I am successfully running ipfw2 in FreeBSD 4.7-RELEASE. Everything seems fine, but it seems like the stats on each of the rules are just _way way_ low. On all rules I notice this. for instance: 65123 556880155 55168583654 allow ip from any to any This shows 55 gigabytes of total trans

Hi While I cant really comment on your code as such, another place this kind of action would be useful would be for IPSEC processing. More often than not, the IPSEC headder bumps the packet size over the limit and so fragmentation occurs, particularly where the IPSEC is being handled by a gatewwa
