Installing Sophos Web WS500 in High Availability (HA)

I can tell you how we solved this in our network.

If you want I can explain it in a mail or so.

Thanks for the reply.

You can type all here for everybody to learn. You can as well send it to my email i.e david@caspertechng.com

Awaiting your kind response.

Thanks

We have deployed our two WS5000's and joined them to our management appliance (SM5000)

The WS5000 nodes are configured in explicit mode.

On the management appliance we have configured them in a loadbalancing setup.

The Virtual IP that is configured with loadbalancing is pointing to let's say proxy.example.intern

BUT: during testing we found out that if the SM5000 is down, no communication is possible to that Virtual IP!!

We got around this to also add a second DNS entry let's say app-proxy.example.intern which is a DNS round robin for  both IP-adresses of both WS5000's.

So in our PAC file we have added these 2 DNS entry's in like this:

// DEFAULT RULE: All other traffic, use below proxies, in fail-over order.

return "PROXY proxy.example.intern:8080; PROXY app-proxy.example.intern:8080";

During testing we saw this was working alright it is not ideal but as close to HA as we wanted.

Thanks.

Do you have any documentation/video tutorials i can follow to achieve this.

Thanks
