if_bce tx / rx tick limits
Hi, i wonder about the bce driver's tx / rx tick limits (ticks and ticks_int are limited to 100; otherwise default value (80) gets used) (if_bce.c line 921 / 933 .. ) On DragonFly BSD the values can be set much higher (such as 1000 ..) which would be great in a high-traffic setup. (On linux there's no limit too as far as i remember) Is there any reason why its limited down to 100? Thanks Florian P.S. I'm sorry if this was the wrong mailing list for it; i don't know whats the right list for this (probably net or driver ?) ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
PF NAT issue with 9.0-BETA3 and RELENG_9 'head'
Hello,
i recently switched a router in our test-environment to FreeBSD 9.0-Beta3
(and after things didnt worked ... checked out the current RELENG_9
and recompiled kernel world .. )
Problem:
After 5 - 15 minutes NAT stops working (normal routing still works.)
Network Utilization: about 40 MByte/second, which gets routed
only a few kbit/s are getting natted (NTP Syncs and such ... )
When i took a look on the nat rules (via pfctl -vv -s nat)
the rules gets evaluated; but nothing matches anymore...
State Table helds about 9500 Entrys,
Source Tracking Table about 300
Software / Configuration:
pf, carp
pf.conf:
set limit src-nodes 55
set limit frags 32000
set timeout { adaptive.start 53 adaptive.end 54 }
set timeout src.track 600
set timeout frag 30
set skip on lo0
set skip on igb2
set skip on igb3
set skip on bce0
set skip on bce1
set skip on pfsync0
#set skip on internal
#set skip on carp3internal
nat on public from 10.5.0.0/16 to any - { public }
carp device holding the internal gateway ips (10.5.0.253 .. ),

Okay, thanks i'll post it there.. i missed that there's also a pf-related list, sorry Has anything changed from 8.2 to 9.0 that i missed to consider in configuration?
