Beste forumleden,
Ik heb een probleem met mijn Cisco 877W op een Telfort 20 Mbit lijn, wat met de bijgeleverde ZyXEL router niet voorkomt op deze lijn. Ik hoop dat iemand ervaring heeft met een soortgelijk scenario en hulp kan bieden. Het probleem: nadat de Cisco gestart is heb ik een prima internet verbinding, zo tussen de 14-16 Mbit wat het ZyXEL modem ook presteerde. Echter, na een bepaalde tijd (aantal uren of slechts minuten) zakt de hele internet verbinding in elkaar op de Cisco en eindigen de computers met snelheden tussen 10-150 kbps. Zowel bij wireless als wired is dit het geval.
De momenten waarop dit gebeurd is volkomen onregelmatig, hetzelfde geldt voor de duur van de stabiliteit. Een "shutdown" en "no shutdown" op de ATM0 interface lost het probleem op, evenals een "reload" of power cycle. Hoelang het duurt voordat de verbinding dan weer in elkaar zakt is altijd weer verschillend.
Ik heb het vermoeden dat er iets mis is met mijn Cisco config, aangezien de ZyXEL wel werkt naar behoren. Echter, als ik de config van mijn ATM interfaces vergelijk met andere mensen op dit forum of op het internet lijkt hier niets aan te ontbreken.
De hele config is met SDM in elkaar gezet omdat ik niet erg ervaren ben met Cisco, vast en zeker staat er hier en daar te veel of is het te uitgebreid (met name op het firewall gedeelte). In ieder geval staat de firewall potdicht, nu heb ik eens iets gelezen over de 10.0.0.0 range die open moet staan voor de ADSL provider i.v.m. het e.e.a., zou dit ermee te maken kunnen hebben?
Alvast hartelijk dank voor de geboden hulp.

If you have already used the username "cisco" to login to the router and your IOS image supports the "one-time" user option, then this username has already expired. You will not be able to login to the router with this username after you exit this session. It is strongly suggested that you create a new username with a privilege level of 15 using the following command. username <myuser> privilege 15 secret 0 <mypassword> Replace <myuser> and <mypassword> with the username and password you want to use. ----------------------------------------------------------------------- ^C banner login ^CAuthorized access only!
