pppoe, Too many LCP NAKs sent - abandoning negotiation

dotfish · Aug 22, 2011

Hi,
This is my first post, its regarding the pppoe connection to my ISP. I am able to connect to my ISP from a Windows system without any issues but when I try connect from my freebsd system it doesn't connect, looking at ppp.log file gives me "tun0: Phase: deflink: Too many LCP NAKs sent - abandoning negotiation" message. I tried my best to get help with google but could not find much. Few details which may help are below
system Freebsd 8.2
network interface is em1
ppp.conf is

Code:

default:
        set device PPPoE:em1
        set ifaddr 10.0.0.1/0 10.0.0.2/0 0.0.0.0 0.0.0.0
        set log Phase Chat LCP tun command
        set speed sync
        set mru 1492
        set mtu 1492
        disable ipv6cp
        enable dns
        disable pred1 deflate lqr
        deny    pred1 deflate lqr
        disable ipv6
        accept chap
        add default HISADDR
bsnl:
        set device PPPoE:em1
        set authname <loginname>
        set authkey <password>
        set timeout 0
        set login
        set dial
        enable echo

Output of ppp.log
