Fernando,
What you have done is a great test to show that the XS is correctly setup and working.
Now we have to make some changes. There are a couple ways to do this but I'll suggest one:
-Disable DHCP on XS
-Enable DHCP on 2wire
-Configure eth0 IP address on XS: 192.168.1.253
-Configure on eth0 GATEWAY = 192.168.1.254
-Configure DHCP server on 2wire to point to 192.168.1.253 for DNS
The goal is for the XO to receive the following ip configuration:
IP address 192.168.1.1-252 (check by runinng ifconfig)
Gateway: 192.168.1.254 (check by running route and look at default gateway)
DNS Server: 192.168.1.253 (check by running cat /etc/resolv.conf)
Please let us know.
Regards,
Reuben
