Hi Gerald,<br>
<br>
To expand a bit on what Martin wrote, the XS sits between the XOs and the<br>
world (rest of the network). You haven't said how the XS and AP connect to<br>
each other, but I'm assuming it is via ethernet, that is the AP is not<br>
directly attached via USB. If that is the case the XS needs two ethernet<br>
cards, one for the AP and XOs, and another for the world. In all likelihood<br>
these would attach to different VLANs.<br>
<br>
I have fiddled with manually configuring ethernet on the XS and have wasted<br>
a lot of time. If I were in your situation, I would simply reinstall the<br>
latest version of XS, especially since it is suited to your architecture and<br>
you probably don't have anything at this point that you need to preserve.<br>
<br>
Ask your network guy for a static IP address and addresses of the DNS server<br>
and gateway for the world. During the install use these values to set up<br>
eth0. Attach this ethernet port to the VLAN that includes external access<br>
(not the XOs and AP).<br>
<br>
XS install will set up eth1 with the proper IP address along with DHCP, DNS,<br>
Gateway for the XOs. Attach this ethernet port to the special VLAN created<br>
for XOs and attach the AP to the same VLAN. If the AP has a static IP<br>
address it needs to be in the subnet of eth1 and not in the range of DHCP<br>
address supplied by the XS, though letting the AP get its IP address via<br>
DHCP from the XS may also work. Eth1 addresses will probably start 172.18.<br>
It is also possible that what you think are eth0 and eth1 are reversed by<br>
the install and there is a command to switch them, but a little<br>
experimenting will also reveal what's what.<br>
<br>
My guess is that you had the XOs in the same VLAN as the XS's external port<br>
before, which is why ping worked, but nothing else.<br>
<br>
Hope this helps,<br>
<br>
Tim<br>
