Dear Expert, I have Cisco 877 series Router, this type of router has 1 ADSL WAN port and 4 Ethernet LAN ports. The device will be connecting into the SHDSL circuit. It cannot use the ADSL WAN port since the SHDSL circuit is using Ethernet ports. Instead I will be using the LAN Ethernet ports (int Fa0) as WAN.
The said router can do the VLAN mapping and can do several VLANS. How can I used the LAN ethernet ports as WAN port for this case.

Hello Carlos,
you need to create a second vlan
conf t
vlan 2
assigns the port that connect to SHDSL to vlan2
int fas0
switchport
switchport mode access
switchport access vlan 2
! configure SVI vlan2 as your WAN interface
interface Vlan2
Desc WAN
ip address x.x.x.x
or
ip address dhcp
no shut
ip nat outside
other ports will be in vlan1 that is your internal subnet
int vlan1
ip address 10.10.100.1 255.255.255.0
no shut
ip nat inside
!
ip nat source inside list 1 int vlan2 overload
access-list 1 permit 10.10.100.0 0.0.0.255
Hope to help
Giuseppe
