What exactly do you want to do with the second connection? You can configure it as a standby internet link using the IP SLA feature. When the first internet link would go down the router would automaticaly switch to the second.

There are many combinations for your question :

  1. your router to one ISP
  2. your router to two individual ISPs

Which option ?

Further to your questions:

  1. do you have own IP subnets ( not loaned from local ISP ) ?
  2. do you have own BGP ASN number ?

If "no" to the above questions, you may have the following questions:

  1. two network links for incoming traffic only ?
  2. two network links for outgoing traffic only ? ( WAN load-balancer is OK )
  3. two network links for both incoming and outgoing traffic ? ( further discussion )

Hi, you seem want to surf the internet only ( but no incoming traffic

-- no internet service to outsider ) ?

many solutions:

  1. floating static routing
  2. dynamic routings
  3. even route map

No, I use the leased line for VPN connection to an other side and e- mail service like (Exchange OWA), and the ADSL for internet only.

So you want the leased to sevice two purposes ( VPN and Exchange ) & and ADSL line for internet surfing ?

Not so difficult for this solution:

  1. VPN is one internet IP mapping + Exchange
  2. default route to ADSL line ( web surfing ) ( all IP routing excluding the item 1 services )

Due to IP addresses of item 1 are fixed ( loaned from the local ISP ? ):

  1. you can only do the load-sharing solution for these two lines; but no resilient network for IP VPN nor Exchange
  2. resilient network for internet surfing, if floating the default route...( but not the load-balance nor load-sharing for internet surfing )
