I've been trying to provide guests that visit our company with wireless internet access. In the past we had a single router set up on our internal network an we just gave them the key to the router. In an effort to try and secure this dangerous hole, I purchased an additional router to separate our internal from the guest networks. However, I'm running into a bit of trouble.
I've attached a rough diagram that shows my basic layout, only there are actually about 25 or so workstations, but the IPs are all static for these. So basically what I've done is run an Ethernet cable from a port in an office to one of the LAN ports of the new wireless router. The internet settings is set to automatically detect. The IP of the router is one from our network, just like I would set up a workstation. DHCP is turned off because our server is providing that and I don't want a conflict.
Now, I have another Ethernet cable that is going to the other port in that same office to the Internet port of the second wireless router. This router is set up on a different IP range than our internal network and DHCP is turned on to issue IPs on that same IP range for the guest computers who connect. The problem is that the only way I could get the internet to work through this router is to set the internet settings to an IP on our internal network. See the attached diagram for an example.
One problem I've come across is this. A few of my workstations now show in their network settings that they are connected to a "Network 2" rather than our "domain". Everything still works the same...the Internet works, the mapped drives to the server, everything...but this is not right. It should be connected to our domain rather than a "work" network called Network 2.
Also, I have my doubts that the guest wireless router is configured properly, but my issue is that my ISP router, and the location where I need to provide guest wireless access, is very far away. If I plug the guest router directly into the ISP router, then from there to my ASA, then I might would have wireless access near the server, but it would not reach to the other end of the building where I need it. So, how should I configure this set up?
Yet again, my workstations are all now installing a "Netgear Wireless Module". The Netgear is the new router I put in for our internal wireless, so i must not have that one configured correctly either. I simply want it to act as a wireless switch, not take over the network.
Please help. I can answer questions if needed. Thank you so much.
