[Server-devel] XS eth1 problems

I'm setting up a XS machine (XS 0.6) that has only one Ethernet port.
This port gets appropriated at eth0 and acts as the primary LAN
interface for XOs to talk to it (via a bridged AP). I also want to get
this box to talk to the outside (WAN) so I'm using a Airlink USB to
Ethernet dongle. Plugging it into the machine triggers the detection
and the dongle gets assigned as eth1.
dmesg says:
eth1: register 'asix' at usb-0000:00:1d.7-2, ASIX AX88772 USB 2.0

udev has the appropriate rule as well.

However, eth1 does not get a dhcp lease from the WAN network. I have
to run dhclient eth1 for eth1 to get a IP. The WAN network is also a
private subnet. 192.168.89.0/24 ifconfig says:

I have had no luck pinging anything on the public Internet either with
an IP or with a domain name. Given that eth0 and eth1 are both
private, how will the XS know how to get to the Internet?
Any help would be great.
cheers,
