Re: route by destination IP address

[Abdelouahed Haitoute]

Hello Baptiste,

We have access to some non-public networks. These networks are only accessible 
via its own proxy server. So based on the IP-address the http-traffic must be 
proxied to the correct proxy server.

I have realized the routing using squid:
cache_peer 172.16.0.1 parent 3128 0 no-query
cache_peer 172.160.0.2 parent 3128 0 no-query

acl host_destip dst 192.168.0.1
cache_peer_access 172.16.0.1 allow host_destip
cache_peer_access 172.16.0.2 allow !host_destip
never_direct allow all

When I visit the hostname http://example/ , squid resolves the 
hostname and checks the IP address to the acl.

It would be great if I can realize it using haproxy. If you have other 
suggestion, let me know.

Hi,

No HAProxy won't do this.
Instead, if you could explain us clearly what is your problem, we may
be able to help you.
For now you just explain what you tried to achieve.

Re: route by destination IP address

I think I’ve found the issue. During test, I’m visiting a hostname 
http://example/. But the acl condition req.hdr_ip(host) will only work if I  
visit http://192.168.0.1/.

Is it possible to let haproxy resolve the domain name and then check the IP 
address?

route by destination IP address

[Abdelouahed Haitoute]

Hello,

I’m trying to route http-requests based on destination IP address. I’ve got the 
following configuration, but unfortunately its not working:

frontend proxy :3128
   acl host_destip req.hdr_ip(host) 192.168.0.1
   use_backend a if host_destip
   default_backend b

I’m expecting all http-traffic with destination IP address 192.168.0.1 to go to 
backend a, but its using the default_backend.

Any help is welcome.
