Local LAN Access issue caused by Inbound access-list at gateway

Hi,

Hosts are not able to access other hosts in the same lan.This LAN is connected to fastethernet of a router(gateway of the hosts) with IOS version 12.4 and an inbound access list is configured on the interface.strange thing is when the access list is removed the hosts are able to access the LAN. IPS is configured on the interface.How is the local LAN traffic going to the default-gateway and how the inbound access list is affecting the traffic ?

Thank you,

Peter

Hi,

The hosts are connected to non cisco switch and the switch is connected to fastethernet with the inbound access-list.The access-list is for cntrolling WAN traffic.

Thank you,

Re: Local LAN Access issue caused by Inbound access-list at gate

are the host on your lan in same network(ie,same vlan or sharing same subnet)??,if not they will anyway go to your default gateway

if yes,

just verify with the non-cisco s/w arp table if they are getting populated properly.

Put a traceroute from a host to another host on the same vlan (with access-list of fastethernet removed) and conform if its going directly or reaching via default gateway..
