Jerry's answer is correct. Edit ifcfg-eth0

That sounds wrong. Maybe I'm misunderstanding what you've done but

 - eth0 is the WAN address. Attaching something to eth1 does not solve
anything unless you've got eth0 and eth1 mixed up...

 - On the LAN side (eth1) don't let the AP act as a router or give
DHCP leases. Set it to be a vanilla AP, no DHCP, routing or NAT'ting.
It is up to the XS to do routing, NAT'ting, handing out DHCP leases
and providing DNS services.

So you are talking about 2 XSs and want one of the servers to be
'downstream' of the other? That'll need a bit of routing glue
methinks. Tell us more about the network topology you're setting up...

cheers,
