I need to configure two public IP on Cisco 1841 ( both on same subnet), 1st IP is on Dailer interface to internet and 2nd IP is on Fa0/0 which is connected back to Sonicwall Firewall.
When I confiure 2nd IP on C1841 Fa0/0 , I gets error message saying 'Overlapss with Dialer0'.
I need to assign 2nd addrress on C1841 fa0/0 becasue its connected to Sonciwall which will also have a public IP address in the same subnet.
How can I confiure public IP on Soniwall. I have 6 public IP available , only one is used for Dialer0 inteface.
Sonnicwall be doing NATing and VPNing.Sonicwall should be visible/pingable from internet using its public IP.
Can you please advise.
