I have just had a 10Meg ethernet turned up and I was given 2 sets of addresses. the first set is:
With a network side,customer side and default gateway.
I was also given:
18.104.22.168/27 for our LAN block.
I am using a 3825 router and want to nat\pat everything inside the network.
Do I need to put another router (1750 with a wic-1enet) between the 3825 and the wan dmarc?
Do I put that 1750 with the "customer side address" on e/0 with a routing statement to route all traffic to the "network side address" which is the address on their device?
If so... then do I put the default gateway address of the public lan pool (209.x.x.x) on the f\0 of the 1750?
Then would I put one of the (209.x.x.x) addresses on the g 0/0 (wan side) of the 3825 and my 172.x.x.x private on the g 0/1 (lan side) of the 3825? and then add the necessary routing statments to make it all work?
Any help would be most appreciated!
No problem. Still a little confused ie. "How does traffic know that my 209.x.x.x addresses are located at the 3825?"
Well the 209.x.x.x address range will be routed by your ISP to the relevant site and the other public address range will be routed by your ISP to the sister site.
