My internet connection is working fine but I can no longer connect from my home to my SonicWall VPN connection at the office. If I take my laptop to my office and connect through a different wireless network it works fine.
I took Norton antivirus off of my laptop, I reset my router (Westell 327W) to factory defaults, I reloaded Sonic Wall VPN client and still no worky. It just shows connecting and I do not get the signon prompt. I opened the SonicWall log and this is what it says "starting ISAKMP phase 1 negotiation, an error occurred, the peer is not responding to phase 1 ISAKMP requests". This used to work and I must have changed something but I don't know what.

This may sounds obvious but have you forwarded the correct ports through sonicwall for your VPN? If you have, do you have any QoS running, it could be worth checking that VPN has priority over VoIP etc. Do you get disconnects all the time or is it only during busy periods? You may be overloading your server, perhaps it's time for more RAM.
It sounds like it might be an issue with the VPN client that is attempting to get to your server at the firm. If you are having issues, first contact the firm's IT department. If they still cannot get you connected then you will need to contact you ISP to make sure that they allow VPN connections.
The default VPN policy rules prevent LAN access, also known as split-tunneling, since this creates a security risk (the ability of the VPN session to be hijacked or compromised through a covert channel).

Two routers on two different sets of internal IP addresses will cause all kinds of conflicts. A VPN router is even worse. VPNs (virtual private networks) are designed to create encrypted tunnels between two computers. The computer its set to connect to must be authorized either as a user or a device with proper credentials. If your VPN authorizes devices based on MAC addresses, then unless your router's MAC address was previously authorized, youre not going to connect. Lets take the router out of the equation for a second. Do you have a working broadband connection from the sonicwall that the router can be plugged into? If you do, then you can treat this connection to your router like its a cable modem or DSL. If this connection has manual settings (such as IP address, default gateway, and primary and secondary DNS addresses) you will need these settings too. Post back and keep us updated...
