'ipfw add nnnnn' accepts rule numbers with leading zeros. However, 'ipfw ... skipto nnnnn ...' fails when given a number with a leading zero; it appears to treat it as octal, but silently ignores non-octal digits (e.g. 02999 is accepted but treated as '2') The man page does not say that 'skipto' treats rule numbers any differently than elsewhere. Trivial to workaround - by dropping the leading zero - but wasted time trying to work out why my ruleset wasn't working! >How-To-Repeat: # ipfw add 00500 skipto 02999 ip from 1.2.3.4 to 5.6.7.8 00500 skipto 2 ip from 1.2.3.4 to 5.6.7.8 # ipfw add 00600 skipto 03777 ip from 1.2.3.4 to 5.6.7.8 00600 skipto 2047 ip from 1.2.3.4 to 5.6.7.8 # ipfw list ... 00500 skipto 2 ip from 1.2.3.4 to 5.6.7.8 00600 skipto 2047 ip from 1.2.3.4 to 5.6.7.8 >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
