we have a customer with an ASA5510 and the service provider is supplying dhcp on the outside connection to the ASA. even though this is the same ip everytime they instead we have dhcp setup.
about once a week the firewall stops the internet connection, we think its the same time as a renew is issued from the provider to the ASA and it stops internet traffic and only comes back after a reboot.
config for outside is
ip address dhcp setroute
version is 8.0(3) anyone any ideas if this is correct or do you need an access list to permit this as well
