Hello,
I am trying to setup relayd for loadbalancing on my DNS servers.
The problem is that relayd seems to handle only TCP connexions, UDP isn't
taken into account.
I found a known bug on openBSD 4.2, but I am using openBSD 4.4.
I've tried the same setup with a relay, and still have the same problem.
Where am I mistaking ?
# pfctl -a relayd/DNS -s nat
rdr inet proto tcp from any to 10.31.33.254 port = domain (tcp.established
600) -> <DNS> port 53 round-robin
# cat /etc/relayd.conf
node1="10.60.0.101"
node2="10.60.0.102"
node3="10.60.0.103"
squid_int="10.31.33.254"
dns_int="10.31.33.254"
# Global Options
interval 5
log updates
prefork 10
timeout 1500
table <squid> { $node1 , $node3 }
table <DNS> { $node1 , $node3 }
redirect "squid" {
listen on $squid_int port 3128
forward to <squid> mode roundrobin check tcp
}
redirect "DNS" {
listen on $dns_int port 53
forward to <DNS> mode roundrobin check tcp
}
Relay config :
dns protocol "dnsfilter" {
### TCP performance options
tcp { nodelay, sack, socket buffer 1024, backlog 1000 }
}
relay dns {
### listen and accept redirected connections from pf
listen on $dns_int port 53
### apply web filters
protocol "dnsfilter"
### forward to web server(s)
forward to <DNS> mode roundrobin check tcp
}
