hi,

i have a server in china that just gets hammered. so i thought i'd try 
limiting access to three ip addresses only (it's par tof our vpn so we 
don't need or want general access to the machine)

interface eth1 inet src "${access_ip}"
        protection strong 100/sec 200
        policy reject
        server "${services}" accept
        client all accept

and access_ip is set up to be the ip addresses i want to allow in.

now it's logging these udp packets like crazy:

May  4 10:23:40 china kernel: OUT-unknown:IN= OUT=eth1 
SRC=211.148.145.81 DST=216.239.53.9 LEN=62 TOS=0x00 PREC=0x00 TTL=64 
ID=26267 DF PROTO=UDP SPT=33008 DPT=53 LEN=42
May  4 10:23:42 china kernel: OUT-unknown:IN= OUT=eth1 
SRC=211.148.145.81 DST=66.102.11.9 LEN=62 TOS=0x00 PREC=0x00 TTL=64 
ID=26268 DF PROTO=UDP SPT=33008 DPT=53 LEN=42
May  4 10:23:44 china kernel: OUT-unknown:IN= OUT=eth1 
SRC=211.148.145.81 DST=203.134.64.66 LEN=62 TOS=0x00 PREC=0x00 TTL=64 
ID=26269 DF PROTO=UDP SPT=33008 DPT=53 LEN=42

what's really strange is no IN, out is the interface, and SRC is the 
address on the interface.

does this mean anything and should i add something to my configuration. 
other than this it seems fine.

thanks

rick
