configuring 2620 for ISDN dial in (no callback required)

Fritz,

One issue you will need to address is the lack of modems in the router... Your users are going to have to dial-in with ISDN instead of the standard analog Modem.

You probably want a "dialer pool 1" on Dialer1. You don't seem to have done anything about assigning IP addresses.

there's a four-port BRI card in the chassis.

yap, that's the way it is intended to be.

best,

hi dan,

thanks for you hint; is that IP address issue fixable by assigning a (static) IP address to each (used) BRI port or can a pool be defined that is then used on demand?

thanks & best,

fritz

There are many ways to do this. You could assign a static address to each BRI line or you could make them unnumbered and share the Ethernet's address. You also need addresses for the clients. If you trust the clients you could let them come with addresses of their own choosing. You could also assign their addresses from a pool. Associating specific addresses with particular username/password pairs starts to get tricky and might require an external authentication server.

hi dan,

thanks for your reply. IMHO it'd be the easiest solution to keep (is that i can keep that actual configuration, 'no ip address' on the appropriate BRI interfaces?) the interfaces unnumbered. do i have to NAT between the router's ethernet interface and the BRI interfaces?

i'd like to keep the setup as simple as possible. there's a maximum of two users dialing in at the same time, and authentication should also be kept very non-complex. no need of assigning certain IP addresses to certain users or similar things.

so, keeping the config the way it is, is there a chance to get this thing up and running?

thanks & best,

The reason you can have no ip address on the BRI interfaces is that they are part of a dialer pool. This just moves the requirement for an address to the dialer interface.

The dialer interface could be unnumbered.

That depends entirely on what you are trying to do...

You realize that each BRI typically gives you two 56k or 64k channels, right? Four BRI ports seems like overkill for two users. Also, I just noticed that you don't have any spid assignments.

There's more to add. I could try to extract a similar configuration from a running system for you, but it doesn't use dialer pools (just one BRI).
