Ok, I am very noob at this, but what I have is an MPLS network between currently 5 sites currently, we are adding a new site.  So I have 2 2811's one at main site(division) and one at remote site(40) All internet needs to flow through Division site.  I am basically asking someone to look at my configs to see if i've succesfully accomplished this..thanks a ton in advanced.  Attached are the configs.

Jason,


As you are advertising the default route via BGP from your main site, you must have it in your remote site installed in routing table.

Hi,


The main site configuration appears to have Internet Gateway connected to your LAN interface. Is it managed by you?.


I see NAT configuration at main site and private address seems to be NATted to private again. Any specific reason?.

yes, there is a sonicwall device which is the (10.24) address. it handles filtering etc.  so there was an issue with nat from the remote sites to that sonicwall device, so added another Ip  10.13 and natted everything to that, which let traffic bound for internet go out properly through firewall.  Not the prettiest config I know..but the goal is to get everything up and then tweak it the way we want.

oh ok, so becuase the main site is advertising the default route via bgp, the remotes sites will have that in their table automatically?  So no further config is needed at the remote site?
