Japanese internal subnet

[DaNNetworks]

Hello everyone,

I have a customer with an internal subnet 110.0.55. which causes a lot of issues.
traffic is also routed outside which is not desirable.

We have started a migration project to phase out this subnet but until then I need a workaround, does anyone have a good tip to temporarily keep this traffic internal?

Thanks in advance!

You can create an outbound firewall rule to block traffic from that subnet on the WAN interface. If you need outbound traffic from there, you need an outbound NAT rule.

Thanks, going ahead and try that!
