Cisco 877W & SSL VPN Gateway

[Dannyrae74]

Hi I'm running a Cisco 877W router IOS C870-AdvsecurityK9-m version 12.4

I need to install a SSL VPN Gateway which has both an internal and external interfaces.

This router only supports 1 Vlan

How do i present an external port to the Cisco 877W router's 4 port switch??

Thanks inadvance

the wan interface is an external port?
can you do a show ip int br on that router..

what interface is your public ip showing up on?
is there a dialer.. or FA0/4 maybe?
