We are installing a Sonic Wall on Fastethernet0. So I will be removing the NAT statements on fastethernet0 and serial0. I will also No out all the IP nat. I will apply 24.75.x.x 255.255.255.224 to fastthernet0. On the other side will be the sonic wall with another free public IP of 24.75.x.x 255.255.255.224. The natting of the rest will take place in the sonic wall.
My question is, because I already use ip address 24.75.X.X 255.255.255.224 on ethernet0. When I apply another IP with the same subnet on fastethernet0. Will that cause routing issues? If So how should I correct it?
1) take ethernet0 (it has its public IP and one other public ip) Should I split it up to 24.75.x.x 255.255.255.252 and then then 24.75.x.x 255.255.255..240 ?. But I don?t have enough free IP?s to do this?
Re: Configuration assistance with a 1700 series router.
just a suggestion... why not change the nat pool to reflect the wan IP of the SonicWall, put the SonicWall on eth0 with the phone system using a small switch. Remove nat statements and add ACL for LAN access. This will leave you a way around the SonicWall via fasteth0. I have SonicWalls set up in this fasion and have found the need for having LAN get around them.
This is oversimplified but you should get the idea.
