Hi!! I have a cisco 2811 router with adventerprisek9 12.4 ios version, I have all configured, ios firewall, ips etc... The current ports Im using it are FA0/0 which is for lan, and FA0/1 which is for wan... I got nat to one ip which is also used for the webvpn and vpn connections, my company got around 50 users.

The problem its when I ping any outside station I got a ping succcess of 80% ... is like 3 in 3 seconds im loosing 1 datagram. Internally I ping sucesseful without any problems at all... what could it be this problem? I can ping my gateway IP and its 100% but after that its always 80% ... Really need help! any advice? thanks

e.g. DEgateway#ping Protocol [ip]: Target IP address: 158.43.128.72 Repeat count [5]: 100 Datagram size [100]: Timeout in seconds [2]: Extended commands [n]: Sweep range of sizes [n]: Type escape sequence to abort.

Sounds like a circuit issue. From the router, ping the next hop on the wan circuit and see if you still get ping loss. If you do, you've found the problem.

I forgot to include, this is the output of the interface which connects to the outside world, my connection is:

LAN=A6-------------------------=A6CISCO2811=A6-publicip-----------=A6ROUTER= .ISP=A6------LEASEDLINE

The line btw cisco2811 and isp router its working at half duplex, I have fitted the router 3weeks ago. Everything there is in my premises.
