Hi all

Could someone please check my config as i'm not getting any pings back

My idea is use a dialer to connect to the modem to access the internet, the modem was supplied by the ISP

anyone?

Look at the good example and solution recent post: you need nat inside and our side interface configured and match the NAT ACL.

hi balaji , i tried a sub-interface lastnight but it made no differnce

Its strange even debugging only gives the below info, no negotiation process just the below
