Is cisco 1841 stateful?

Hi all. I understand that cisco1841 firewall function is stateful. But if my cisco 1841 comes without the firewall function enabled, would my 1841 be stateful? Thks in advance.

If you mean "stateful" in terms of a stateful firewall then no it wouldn't. You can use access-lists etc.. but these are not stateful in the way the firewall is.

If you don't enable the firewall functionality (ip inspects), then no it's not stateful. If ip inspects are configured on the router, then it becomes stateful.

Hi Jon,

Thks for your reply. Now i understand that routers are normally not stateful compared to firewalls. I realised that if you do not specify any accesslist on your router it would allow all incoming/outgoing traffic. However if you specify the traffic to allow in your access-list it would allow only that traffic and deny the rest. This is quite different from firewall which is implicit deny all by default.

I don't know if the 1841 supports this feature, but without the firewall feature set, "Reflexive Access Lists" are stateful.
