Making Logical Interface on WAN port

Unanswered Question
Sep 16th, 2009

I am trying to make logical Interfaces on my Cisco 2811 Ethernet WAN port,

I will use two internet connections on this port,, both connections will be terminating on a layer 2 switch, D-Link, and the switch will be connected to the Router,

Is it possible?????

The router asks me to first make this port for ISL or 802.1q....

I have this problem too.

Yes it is possible to do this.

what i will suggest is that u can create a trunk between router and the the D-link switch. Please revert for any more clarification. Also put the logs in the next post, if u face any more issues

You need a switch with 802.1q VLAN support, it's quite possible the one you have doesn't do that, so get a cisco a linksys switch.

ok.. lets assume that I have it... then....

should I configure it the same way we do Inter vlan Routing???

Should I be able to configure Soft IPsec VPN on the router????

and the users will communicate with 2 live IPs,, I mean,, some users will use one , and the others will use the second one,,,

As well, I want to configure the site-to-Site VPN...

The main Objective is to use only one ethernet WAN Port...

You can do that.

If you have no experience in configuring routers, VPN etc, I recommend you hire a certified professional for safe results without business-affecting mistakes.

I am CCNA Certified,,

Actually due to short down time, I want to complete the documentation first.. and want to ensure that this will work,
