    Hi,

    I´m trying to run a 4.X box with multiple PPPoE connections (_not_ as a PPP
    bundle or something like that).

    Only about 5 connections come up, all further connections fail
    with the error message:

    Warning: iface add: ioctl(SIOCAIFADDR, x.x.x.x -> y.y.y.y): File exists
    Error: ipcp_InterfaceUp: unable to set ip address

    I know that this _used_ to work so I´m really wondering what goes wrong.

    Here´s the relevant parts of ppp.conf:

    test3:
     set log Phase Chat LCP IPCP CCP tun command
     set device PPPoE:vlan3:
     set phone 1234
     set authname test3@something
     set authkey my_pw
     set mru 1492
     set mtu 1492
     set timeout 0
     set speed sync
     set dial
     enable dns
     set ifaddr 10.0.0.1/0 10.0.0.2/0 0.0.0.0 0.0.0.0
     add 195.24.114.101/32 HISADDR

    test4:
     set log Phase Chat LCP IPCP CCP tun command
     set device PPPoE:vlan4:
     set phone 1234
     set authname test4@something
     set authkey my_pw
     set mru 1492
     set mtu 1492
     set timeout 0
     set speed sync
     set dial
     enable dns
     set ifaddr 10.0.0.1/0 10.0.0.2/0 0.0.0.0 0.0.0.0
     add 195.24.114.102/32 HISADDR

    test5:
     set log Phase Chat LCP IPCP CCP tun command
     set device PPPoE:vlan5:
     set phone 1234
     set authname test5@something
     set authkey my_pw
     set mru 1492
     set mtu 1492
     set timeout 0
     set speed sync
     set dial
     enable dns
     set ifaddr 10.0.0.1/0 10.0.0.2/0 0.0.0.0 0.0.0.0
     add 195.24.114.103/32 HISADDR

    [etc]

    Some explanation:
    basically the box is connected to about 12 DSL modems. I want to have traffic
    through all of them and do some statistical analysis. In order to send data
    through all those particular modems I need to set one default route and
    multiple host routes to the gateway HISADDR - in case you are wondering about
    the routing line.

    Some more details from the ppp.log:

    Everything seems to work fine in PPP but when it comes to assignin the
    negotiated IP adress to a tun interface something seems to go wrong.

    I´m really lost here ... anyone have an idea?

    Thanks,

    Emre
