Is there more than one VLAN tag making it to the unmanaged switches you mentioned? Unmanaged switches tend to be unpredictable when presented with multiple VLANs (and some don't even work with one VLAN). The upstream port may get confused about which VLAN the switch is participating in, in one VLAN at a time, and a reboot may have reset the upstream port ...

I was able to find the solution to this problem by making a change to the Active Directory user that was trying to access the resource. Under Account -> Account Options: check "Do not require Kerberos preauthentication"

You had to use tunnel-based VPN and set the appropriate route inside Network->Routing table. For more information, consults the Administration Manual.

Is the SonicWall able to resolve "dc1" IP address? You can test that by using the "Diagnostic page" of the appliance, under "Status menu"

I'm unfamiliar with the 2400 model, but on our SonicWall (a TZ205 running 5.8) we achieve this by adding the interfaces to the LAN Zone and configuring them as a PortShield to the primary LAN interface (X0). Portshield can/does add some extra security, but effectively treats the interfaces as switch ports on the same network. This is configured via the ...

I turned off my router. I prayed to God for 30 seconds. I turned on my router. The SonicWall Global VPN client continued on past the Acquiring IP Address and I got connected and I was able to login in to my remote desktop to do my work. Problem solved.

You can throttle sites in sonicwalls. Its somewhere like Application Firewall -> Application Objects -> Add new Object From there you can say I want to limit youtube to only a set % of the total bandwidth. Check out the following for more info http://community.spiceworks.com/how_to/1949-sonicwall-application-firewall-setting-bandwidth-limit

It does support VLANs but not the all range: http://www.sonicwall.com/downloads/DataSheet-TZ_Series-US-TD-567.pdf

The sonicwall should have a "VoIP" tab on the main menu. Is "Enable consistent NAT" selected? That will help. You shouldn't need the SIP transforms, but if you can post a screenshot or that screen we can try a few things.

If it's a sip trunk, you may be able to get away with telling your PBX its IP is your "external" IP, and forwarding tcp/5060 and udp/[rdp range] to it in the sonicwall. The rtp range will be configurable in your pbx. Because you only need one sip endpoint (the pbx - all your phones talk to the outside world via the pbx) this shouldn't require stun or ...

According to SonicWALL documentation on the Layer 2 bridging: Layer 2 Bridge Bypass is a physical X0-X1 interface bypass relay currently implemented on the SonicWALL NSA E7500. This feature is sometimes known as “fail to wire”, meaning that the LAN-WAN connection reverts to a straight-through connection if the SonicWALL appliance experiences a ...

It's an IPV6 issue, if you go to console and open your ppp log you will notice an IPv6 query every 3 seconds until it times out. You need to tell the ppp daemon to not try IPv6. To do this create a text file called options.txt with the following string: ipv6cp-max-configure 0 Save that file to the etc/ppp directory. You need to be root or sudo cp it via ...

You don't mention how your Firewall is setup. Typically X0 is LAN and X1 is WAN. So by default, traffic from X1 to X0 is blocked. But I don't think that is the problem. The 10.1.0.0/16 doesn't have a routable interface to 172.16.5.1 on the sonicwall. the subnet masks prevent it. even if you add a static route, you still need a routing interface on the ...
