Why would Tomato terminate my WAN connection?

    Running Tomato 1.25 on WRT54GL. Just noticed this in the log this morning:
    As I read this, Tomato decided to send LCP termination. Why would it do that? Or have I misunderstood? Is it that my ISP sent the termination, and Tomato was sending an Ack?

    ACK means responding to an LCP termination request. May have come from AC or modem. Or maybe ISP. We would expect to have seen a "received LCP termination request" message in the log, though.

    It doesn't look like Tomato initiated it.

    Might want to look at the modem's log, if there is one.

    Looks rather like ISP problem... I also have this few times. I would be not worried about that if not happening frequently.

    I'm just curious; it isn't really a problem.
    I'm using a Linksys ADSL2MUE modem with Routertech 2.91.1 firmware; modem is in bridge mode.
    Modem log doesn't show anything obvious although may not be set up properly (it is showing incorrect dates).
    I'll work on getting modem logging correct and reopen this if needed.

    FWIW I think the Tomato ack is acknowledging the termination request from your ISP, not initiating it.

    Your modem in pppoe full bridge mode will not have internet access so cannot update its time. I have seen some attempts to allow a bridge modem to do this - basically you need to assign the router WAN port a modem range local IP address as per the method to access the modem diags from the router, assign the router as the modems default gateway, then add router firewall rules to allow it to route ntp traffic from the modem and route to the internet.

    Just curious... how often do these disconnects occur? Are they at exactly-regular intervals? Or at different time periods?

    This thread is probably a different problem to yours, but you may find some of the advice helpful....

    Odd, though, that Tomato doesn't record the termination request.

    Ah yes, of course. I'll have to have a play. Are there any examples online of how to do this?

    Very irregular, so far as I am aware. In any case, Tomato reconnects pretty much immediately, so it doesn't really cause a problem. Mostly I just notice that the connection uptime has been reset. Interesting thread though.
