请教PF做负载均衡的问题

右亦非

我的pf.conf如下:
# macros
int_if = "em0"
ext_if = "em1"

tcp_services = "{ 22, 80 }"
icmp_types = "echoreq"

priv_nets = "{ 127.0.0.0/8,  172.16.0.0/12, 10.0.0.0/8 }"

webserver = "{192.168.18.90}"

# options
set block-policy return
set loginterface $ext_if
set skip on lo0

# scrub
scrub in all

# nat/rdr
rdr on $ext_if proto tcp from any to any port 80 -> $webserver port 80

# filter rules
block all

block drop in  quick on $ext_if from $priv_nets to any
block drop out quick on $ext_if from any to $priv_nets

pass in on $ext_if inet proto tcp from any to ($ext_if) \
   port $tcp_services flags S/SA keep state

pass in log on $ext_if proto tcp from any to $webserver port 80 \
    flags S/SA synproxy state
pass in on $ext_if inet proto tcp from port 20 to ($ext_if) \
   user proxy flags S/SA keep state

pass in inet proto icmp all icmp-type $icmp_types keep state

pass in  on $int_if from $int_if:network to any keep state
pass out on $int_if from any to $int_if:network keep state

pass out on $ext_if proto tcp all modulate state flags S/SA
pass out on $ext_if proto { udp, icmp } all keep state

但出现问题如下:
root</etc>pfctl -ss
self tcp 192.168.18.90:80 <- 192.168.18.103:80 <- 192.168.18.155:1479       CLOSED:SYN_SENT
self tcp 192.168.18.90:80 <- 192.168.18.103:80 <- 192.168.18.155:1480       CLOSED:SYN_SENT

直接访问192.168.18.90是可以的,请问有谁知道问题在哪吗

无奈,没有回,自已顶了

剑心通明

webserver 得是通过OB上网的才可以用rdr吧

负载均衡你怎么在实现？建议看看http://www.unix-tutorials.com/go.php?id=280
