In this environment ZS works now as expected.
Now i ask before my next mismatch causes trouble:
Next step are three another lines (pppoe) balanced with the default one.
Am i right to enable NAT on this devices?
Am i right to change the default gateway to a balancer gateway?
Am i right to point the traffic to a special server with a balancer rule to a dedicated gateway?
Is it a good idea to enable rip-v.2 on all devices?
Thanks in advance
