Ok here is the plan:
We have a customer who needs a solution as follows:
Two offices connected via ADSL business line 2/512Mb.One Panasonic KX-TDE-200 VOIP PBX telephone system one both sites to which up to 5 phones will be using the tunnel for voip and 3 for data.One router that can do VPN and Firewall protection and one switch that will connect approximately 20 users.
I was thinking of putting a cisco switch 2960 and a cisco 1841 that will do the VPN and the firewall.The panasonic PBX will be connected on a different vlan on one of the ports of the switch and switchport that to voice.I am concerned if i am thinking the correct procedure here and will like to know what else i'm missing here so as to make the system work as efficient as possible. I m ready to hear suggestions...
