I currently have a cisco 837 router connected to my DSL line. This is working fine, it has an onboard firewall but not the best.
I have just purchased a sonicwall TZ170, and need to position this behind the 837.
We need to 837 as this has the built in Modem in it for the DSL. I have an 8 external IP Addresses.
How do i do this?
I have thought of linkig the two up in another subnet i.e.10.10.10.0/C but how would i configure the routing??
Thanks for you help!
