  2. I don't know about the smallest, but if I understand correctly, the
    837 has a four-port switch, one port of which can be changed into
    a full LAN interface.

    831 with a particular IOS can have up to 3 interfaces.

    1 WAN e4 (? - i don't know how it is called)
    1 Ethernet (normally linked to the 4 switch ports) e0
    1 Ethernet (linked, when put in no shutdown mode, to FastEthernet 4)
    I used an 837 as a ethernet router substaining rates up to 2 Mbits/sec (due to bandwidth limitation on a router behind
    the 837)

  6. Hi!
    Thanks fpr all input so far.
    I need routed interfaces.
    I think I will go with a used 1720 with 2 WIC-1ENET.

  7. Ah, you're in Germany; if I understand correctly, the law there
    requires that the software be transferable. Most places in the world,
    you would encounter the problem that the software license does not
    [normally] transfer when an IOS router is sold; by the time you
    pay the fee to "relicense" IOS from Cisco, an 83x would likely be
    less expensive.

    Even in your location where [if I understand correctly] you are
    entitled to continue to use the license that is already on the
    machine, if you find that you need to upgrade to a newer IOS version,
    the cost to do so could be high, depending on the features you need.
    It probably is not -so- bad for a 1700 series, but by the time of
    the 3600 series it can be a big expense.
