Hi all,
I have one Cisco PIX 501 connect by outside interface to a Telecom Router. This Router show his state by web page. The router automatically each 5 minutes updates his tables and publish IP Addresses of each host connected, on his web page.
I think that Router capture IP Adresses of any host connect, by sending Gratuitous Arp. When this happens, my PIX 501 outside interface becomes not operational however its state is UP - UP.
It seams doesn't work to Router's IP only.
In this situation internet results unrechable.
I test by ping (I'm connect to PIX by his serial interface to my PPC) connection between router and pix.
On my PPC I have also open Internet Explorer on Router Web Page, when I refresh this page the Router update connected Host IP Address list in this moment it is systematic: connection loose.
I also enable pix log but last log information avalaible is ping from pix to router ip address.
Cane anyone help me???
Tks all.
