Hello. I am new to Cisco products and this forum.
I bought 1841 for my organization, but I found out that I need to upgrade IOS in order to use Firewall, NAT and VPN.
Looks like I need to upgrade IOS. Because I did not buy it through Cisco reps, I could not get any help about it.
I am wondering if IOS upgrade can be done for free or the item description on the online store I bought from had a error.
I just need a new router for around 100 hosts.
Because 1841 does not those features, I am thinking of returning the item.
Any advice is appreciated.
Thank you very much.
