Can you ifconfig -tso4 on the interface and see if that helps? Let me know the results. Is this still a problem? I think we can close it. Moved to 11 and pf altogether. |
Hello, FreeBSD 10.0-STABLE built from last night. The kernel was compiled with: options IPFILTER options IPFILTER_LOG options IPFILTER_LOOKUP options IPFILTER_DEFAULT_BLOCK # ipf -V ipf: IP Filter: v5.1.2 (608) Kernel: IP Filter: v5.1.2 Running: yes Log Flags: 0 = none set Default: block all, Logging: available Active list: 0 Feature mask: 0x4e Here is the ruleset: # ipfstat -in @1 pass in quick on lo0 from any to any @2 block in quick on vmx0 from any to any with frag @3 block in quick on vmx0 proto tcp from any to any with short @4 block in quick on vmx0 inet from any to any with opt lsrr @5 block in quick on vmx0 inet from any to any with opt ssrr @6 block in log first quick on vmx0 proto tcp from any to any flags FPU/FSRPAU @7 block in quick on vmx0 from any to any with ipopts @8 pass in quick on vmx0 inet proto tcp from 192.168.60.0/24 to 192.168.60.1/32 port = ssh flags S/FSRPAU keep state @9 pass in quick on vmx0 inet proto icmp from 192.168.60.0/24 to 192.168.60.1/32 icmp-type echo keep state @10 block in log quick on vmx0 all # ipfstat -on @1 pass out quick on lo0 from any to any @2 pass out quick on vmx0 proto tcp from any to any port = domain flags S/FSRPAU keep state @3 pass out quick on vmx0 proto udp from any to any port = domain keep state @4 pass out quick on vmx0 proto udp from any to any port = ntp keep state @5 pass out quick on vmx0 inet proto icmp from any to any icmp-type echo keep state @6 block out log quick on vmx0 all I see a lot of BAD packets in the logs while SSH-ing to the box (the transfer speed over SCP is also affected).
