I have a cisco 1720 router with one adsl interface, one fast ethernet and one ethernet. the user had just the adsl portion but now wants to bring in a second isp (cable modem) on the ethernet port. he also has a pix 515 with three ethernet interfaces behind the router.
how do i load balance traffic between the two interfaces?
how will incoming traffic we redirected since he is running mail and web behind the pix?
can this be done?
any help will be appreciated...
