<div dir="ltr">Hello,<div>How do i setup policy based routing with NAT?</div><div>The problem is as follows:</div><div>We have SE600 with two cards 4*10GE.</div><div>Card in slot 2 is uplink card. Here we have 2 uplinks and link to cache node.</div>
<div>Card in slot 5 is downlink card. Here we have 2 downlinks to our network(ports 5/2 and 5/4). Both ports have NAT policy. Cache node requires that customers reach it with public IPs.</div><div>We wish, that traffic from uplinks goes through port 5/2 to our customers, and traffic from cache node goes through port 5/4.</div>
<div>We tried using "forward policy" to set next-hop for traffic from cache, but it seems, that in this case it doesn't go through NAT on the way back from the node. trace looks like it goes through 5/4 to customer network, router on the customer network uses default route for this packets, the packets come back at 5/2 deNAT from public IPs to gray net, then packet is sent through 5/2, because routing information base says, that those IPs are reachable through 5/2(main link).</div>
<div>Besides excessive load we see that cache node serves less traffic(e.g. 700Mbps without forward policy, about 300Mbps with forward policy).<br clear="all"><div><br></div>--</div><div>Michael</div></div>
