[lvs-users] LVS "Passthrough"

Hi folks,

Whilst I've got LVS up and running for load balancing services amongst
realservers that come in on the VIP, this effectively disables access to
that node on its non-VIP (RIP) LAN address.

Is there a way to specify a "passthrough" for these non-VIP packets, so
that local LAN communications can just "pass through" LVS untouched?

I have some cluster control software that intercommunicates between the
nodes on the LAN - it always uses the RIP and not the VIP - and I'd like
RIP-based packets to just be delivered normally to the node, only the
VIP needs the load balancing.

Regards,
Owain

In general there shouldn't be any problems with that: I certainly can
access my DR-ed real servers via their RIP addresses. Maybe you should
describe your setup to help us understand the situation.

Ah, yes. I appear to have confused myself with my own security measures.
I forbade access to certain resources, while I was setting it up and I'd
not undone them since. The "connection refused" is my own firewall
policies, not LVS.

Sorry. I've been an idiot there. Carry on and pretend like nothing happened.

Regards,
Owain
