I cant realise more than two simultaneous internet dialin.
I have a cisco 2821 and three dsl lines.
There are three ethernet interfaces and three dialer interfaces configured. Every dialer works fine but I cant connect more than two dialer at a time.
It seems the router have only two possible virtual-access ports.
Has anybody a configuration with more than two active internet dial-in with PPPOE.

Hi there,
The router can support as much virtual-access as its IDBs supports "show idb", which can't be 2, can you please post your configuration as well as "show idb".
best regards,
Mohammed.

Hi Mohammed,
thanks for your reply.
You are right. I try it again today and saw three virtual-access interfaces.
But I dont get a connect on all interfaces at a time.
The config is not ready but i think it is enough to get the connections.
Here is the config:

Hello,
Did you ever get this config running properly? Do you have an HWIC in this router?
Thanks,
Dan.
03-19-2007 04:51 AM
Hi,
yes I have an HWIC Module.
It was not possible to realice more than two pppoe session on this module.
But I create a third dialin with one of the the fixed gig ports.
So the router runs with three dialins.
Regards,
Sebastian

I think i have found why you cannot have more than two internet dialin's at one time.
conf t
int virtual-access ?
shows:
<1-2> virtual access interface number
If i'm right every dialer interface is attached to a virtual access interface. Thus only allowing you to have two dialer interfaces at one time.
Would this be a limit of the ios? I really need to be able to run four dialin's at one time.
Thanks,
Dan.

Hi Dan,
The problem with the virtual access interfaces is the same problem I find out.
I think you need HWIC-1FE interfaces instead of a HWIC-4ESW. It seems to be a problem with the interface or the internel module slot limitation.
Like I do you can realice two dialer an the HWIC-4ESW and two on the fixed installed ports at the same time so you have four dialin?s at one time.
I think this will work(my config runs with three dialers).
Regards,
Sebastian

Thats a good idea. Would you mind posting your current config. I'm still having some trouble and I wouldn't mind comparing mine with yours.
Thanks,

In this sample I use 3 dialins but it must be simmilar to use 4 dialins. The gig int 0/0 is for internal and the dialer 3 is for internet access. the other two dialer are for vpn but not configured now.

The access-list 101 is not needed in this sample.
It is preparation for VPN (no nat).
