Multiple VPN clients behind home router

    I've got 2 Windows PCs with the Cisco VPN Client behind a home/Linksys
    router. They can both individually establish VPN connections back to my ASA
    and everything works great. But if they both try to connect via VPN at the
    same time the second one effectively disconnects the first. I don't think it's
    an issue with the ASA config. Is there a particular brand/model of small
    business/Home router that will allow multiple VPN connections to the same
    location? I'd rather not put in an ASA at the user's home.
    Thanks in advance

    Have you tried the "IPSec over TCP" setting?

    Small Draytek routers and modem/routers can setup IPsec VPN by themselves.
    You can connect them directly to a Cisco. You can specify a subnet and
    it will route all traffic from/to the subnet. No software needed on
    the systems. You may need a config change on the Cisco.

    This won't work without modifying the ASA config, or at least it doesn't
    work if all I do is change the client, and I'm hoping to find a solution
    that doesn't require a change to the ASA.

    We only do site-to-site VPN when the other site is an actual office, not a
    home worker. I already have to remind them that the laptop is not to be used
    by their kids/family imagine if I had open switch ports just begging to be

    Actually on a Draytek you can configure the switch ports into different
    VLANs and specify which ones can use the VPN tunnel and which ones have
    only internet access. So the kids can plug in their PC on the same router
    but not have access to the company LAN.

    Of course it can be sabotaged.

    Anyone else have suggestions on how to solve this problem?

    Just tried my Draytek Vigor 2820n. It accepted two active Cisco VPN
    client connections from here to the same Cisco box at the office. An
    extremely quick scan of the user manual indicates that two connections
    is the limit. There are other routers that do it - we got round a
    similar problem with a remote office of 3 or 4 PCs six or seven years
    ago - sorry, can't remember the brand we ended up using then, but it
    would have been mainstream and cheap.

    Yes, there is a command in the ASA VPN policy to allow more than 2
    active connections. 2 is the default but you can change it to more.
    The command is:

    group-policy GROUPNAME attributes
    vpn-simultaneous-logins X

    This problem is due to the client side router only supporting 1 VPN passthrough connection. Read multiple VPN connections for more details.
