I am unable to communicate with sonicwall firwall using IP and reason is when I assign the IP address on fa0/0 on router its overlaps with dialer interface ( conecting to internet).
I can't assign public IP addresses on fa0/0 on cisco 1841.( assigned by ISP , 6 IP's) Public IP from the same range is already assgined to dailer interface. Both IP's are on same subnet. I get I get the error message saying overlaps with dailer0.
IP need to establish layer 3 connectivity from Sonicwall to internet to build VPN tunnel.
S0 three IPs on a same subnet.
First IP to Cisco 1841( dialero to internet)
Second IP to the Fa0/0 ( connection to Sonicwall)
3 x IP on Sonicwall
VPN------internet---Cisco 1841 ---- Sonicwall-----Switches--------LAN
Can you please confirm if this setup is possible,
Sonicwall should have public IP address.
