I have a Cisco E4200 as a router running behind my gateway. Previously I used the E4200 for n-wireless because the 3801 HGV-B was only g-capable. I also configured many of the security and access features of the E4200 to meet the needs of our family network. I run the E4200 on a different subnet than the gateway (IP Address 192.168.2.1, Subnet Mask 255.255.255.0, Device range from 192.168.2.100 to 149).
Recently, I had a severe intermittent service problem develop, and the technician replaced the 3801 with a Pace 5031NV. At that time, it was a clean swap. Didn't change any settings on the new gateway; didn't change any settings on the E4200. When this didn't solve the problem, I took the following steps on the RG:
1. Activated DMZPlus on the 5031NV.
2. Rebooted the E4200
3. On the 5031NV RG in Settings -> Firewall -> Advanced Configuration, unchecked Stealth Mode, Block Ping, Strict UDP Session Control.
4. On the 5031NV RG in Settings -> Firewall -> Advanced Configuration, I checked everything under Outbound Protocol Control except NetBIOS.
5. On the 5031NV RG in Settings -> Firewall -> Advanced Configuration, I unchecked NetBIOS under Inbound Protocol Control.
6. On the 5031NV RG in Settings -> Firewall -> Advanced Configuration, I unchecked all the Attack Detection checkboxes (7 of them).
7. Disabled WiFi on the 5031NV RG.
When the technician was here, I couldn't really get anything out of him about diagnostic results (if there were any). He just swapped the gateway. None of this has solved the problem - internet has been spotty and for two days I haven't been able to make outgoing (VoIP) calls.Two questions:
A. Setting the phone issues aside, with the goal of running the E4200 behind the Gateway (getting the Gateway as close as possible to a bridge mode), is this setup functional? optimal?
B. Any sense of whether using the RG for my WiFi connection rather that the E4200 would be better or even possible? (further revealing my status as n00b who was lucky to have a stable network for a long time)
Let me know if you need any logs or IP info to address these questions, and thanks very much for the help!
