Multi Wan on cisco router

Nov 04, 2010 1 Replies

Hello I would like to ask your advice and maybe your help :)



I am thinking about this:



A single router with 4 Wic ADSL . I would like to connect a single router that does NAT1-1 to 4 ADSL link RFC1483



LINK1 ip addr 1.1.1.2 - ptp 1.1.1.1 - ip subnet 10.10.10.0/29 LINK2 ip addr 2.2.2.2 - ptp 2.2.2.1 - ip subnet 20.20.20.0/29 LINK3 ip addr 3.3.3.2 - ptp 3.3.3.1 - ip subnet 30.30.30.0/29 LINK4 ip addr 4.4.4.2 - ptp 4.4.4.1 - ip subnet 40.40.40.0/29



Each adsl has a /29 pool of ip addressess.



The "lan" side of the router will be 192.168.1.254/24



From this router I will do a nat 1-1 to private ip addresses, example



192.168.1.1

Document seems quite good to me, doubt I could do better.

Have you tried the setup described there say with GNS3 or just raw dynamips - or heaven forbid real routers:)? I have never used GNS3 since I got into dynamips before it bacame available.

You can add extra routers to use as "servers" for test purposes.

Give it a go and if you have problems get back with show commands illustrating the problems.

iproute 0.0.0.0 0.0.0.0 target-ip

i.e. null ip address with null mask
