Upstream packets from ES1 (and ES2) are sent to 155.1.3.1, where in turn the
router would forward them to the NSP. Downstream packets from the NSP are
sent to ES2.
For upstream packets only (i.e., packets arriving over the DSL ports), the order of
routing precedence is:
1. Source host route
2. Source subnet route
3. Source network route
4. Destination host route
5. Destination subnet route
6. Destination network route
7. Default route
NOTE:
When using source routing, do not use the default route.
