ZyWALL USG Support Notes

NOTE: Default gateways in different interfaces also have priorities. They‟re decided

by the interface Metric. The smaller the metric value, the higher the priority is. Thus,

metric 0 has the highest priority among all the interface default gateways.

If two or more interfaces are using the same metric value, e.g. 0, the first configured

interface gateway will have priority over all other later configured interface gateways

with the same metric value.

1.1.3. SNAT Priority

The picture below shows the SNAT priorities in USG ZyWALL. The priorities will

determine which SNAT rule the USG ZyWALL will use to map the traffic‟s original

source address.
