Hope you are all well?
I'm after a little bit of advice and looking around getting conflicting advice.
So I'm doing a bit of network upgrade to our infrastructure. We now have plenty of Cisco Kit to replace all out Linksys Kit. I don't know the best approach at the moment.
Our current setup is:
Internet --> ISP Router (Linksys) --> Switch --> Cisco 2801 (Setup with VLAN's).
(All clients have the Default Gateway of 192.168.1.1 (the Cisco 2801), this then routes all 0.0.0.0 traffic to the ISP Router with route 0.0.0.0 0.0.0.0 192.168.1.4)
I'm going to replace all the kit including the ISP Router and add a ASA5520.
So do I do:-
1. Internet -->> Cisco 2911 --> ASA --> Switches
(This would mean doing the Inter-VLAN stuff on the Firewall - I did try to get a Layer 3 Switch but couldn't get budget)
2. Internet --> ASA --> Cisco 2911 --> Switches
3. Internet --> Cisco 2911 --> ASA --> Cisco2911 --> Switches
Many Thanks for any help in advance.
