Cisco 800 / Sonicwall Tz170 - Allow Two Networks To Talk?

Jan 11, 2012

I have my modem then a switch, and two gateways a Cisco 800, and a sonicwall tz170.The Cisco isn't managed by me, it's on a 172.18.2.x subnet and I only have about 12 addressable IPs.I manage the sonicwall and have all 254 addresses open. The computers have to stay behind the Cisco because it connects to a VPN that the line of business software uses.

I can't connect the two gateways by VPN because I cant control the Cisco.How can I get these two to talk? I have a new server on the sonicwall network and an old server on the Cisco network. I want the computers to be able to see both servers

Cisco Firewall :: ASA 5510 Cannot Talk To Remote Networks Connected

Mar 20, 2012

We have an inside interface, 192.168.10.0/23We have an outside interface, public ip...We have the ASA connected to 5 site to sites, this is working fine and through the internal interface can access all remote sites and vice vera. These are 192.168.20.0/24, 192.168.30.0/24, 192.168.40.0/24, 192.168.50.0/24 and 192.168.60.0/24,When a user connects via Cisco VPN Client they can see the inside network but can't talk to the remote networks connected, for instance 192.168.40.0/24... whereas an internal user can. I understand that the VPN client connection is seen as an outside connection, not an inside connection... but then I read [URL] and I am confused even more.

Talk Talk Router - Connection Is Suffering Idle Timeouts Daily

May 21, 2012

I've got an aol engineer visiting Thurs.to examine connection loss (since last Weds). But I'm convinced the problem is with the router. But from the tone of the aol tech questions I suspect he's already briefed his engineer to do his best to represent the problem as being either with my computer or positioning of router/filters/condition of wall-sockets - usual getouts.The talktalk router is neww, issued Feb 12, after my original router, speedtouch, started suffering idle timeouts every day.

Cisco :: Avaya Phone Won't Talk With Server?

Apr 17, 2013

When I place the phone on a different subnet, registration failed. The connectivity between the two subnet should be working because I have a desktop computer hook up behind the Avaya phone and the computer can talk with the server without problemThe phone has gotten the IP from DHCP server can I can even ping the IP from phone server. but on the phone it shows "Discover 10.0.10.10" then reboot, again and again. 10.0.10.10 is the IP of phone server. And there is no firewall rules blocking the traffic between the two subnet.Like I said before, if I place the phone on the same subnet as the server it worked. The setting of the switch remain unchanged

D-Link DAP-1522 :: Do Devices Talk Directly

Apr 14, 2013

Do the devices connected to the DAP-1522 communicate directly with each other or do they communicate through the router.My DAP-1522 is set up as a bridge connected to my DIR-825.  The reason I ask is I've set up an HTPC connected to the DAP-1522 and I also have media devices connected to the DAP and am wondering if they'll communicate with each other directly or if they have do it by going to the router and back.  That way I can use my HTPC to serve media to my devices at local speeds.

Outlook Or Google Earth / Talk Does Not Work Properly?

Nov 12, 2011

I have a new Lenovo Ideapad laptop and Im having problems connecting to internet using ethernet cable. The thing is this problem occurs only at one particular place (dorms) because Im having no internet problems at other locations.

It looks like this: I connect using ethernet cable, Windows 7 identifies the network and everything looks normal, but there is no internet when I open a browser (I tried IE, Firefox and Chrome). It just loads and loads and sometimes it loads my Google homepage, but only after approximately 30 seconds or it does not load it at all. The same applies for other pages - they do not load or they load after a minute, but the pages are incomplete, they look like HTML

When I do a ping at CMD, it shows the same problem, the replies are slow or it shows "request timed out". I tried pinging various pages or IPs with same results. The only thing Im able to ping normally is the IP of my network adapter. My IPv4 is set to automatic, but I also tried manual parametres, just in case.I tried 3 different cables, switching antivirus and frewall off, did spyware search, switching IPv6 off, switching WiFi off, reseting the main dorm router etc etc...

Strange thing is that my laptop works perfectly anywhere else (home, work...) so I suppose there is no problem with the configuration of my laptop or network adapter, BUT the internet provider says there is no problem with their network or router since other laptops works normally at THAT location (even my other laptop does work there), so mine Lenovo is the only laptop which is having problems... and when I check the properties of the network, upload is always higher than download, but generally both are very small one more strange thing: I can watch live stream videos using one particular software and I can download torrents quite normally, but loading Google and other pages is a major problem, even Outlook or Google Earth/Talk does not work properly

Cisco WAN :: SonicWall VPN Between 2800

Oct 29, 2012

I have two CISCO 2800 routers tied together over a Metro Ethernet bewteen an HQ location and a Colocation facility.    There are multiple subnets on both sides of the MAN.   All things work in this regard.
 
I added two new Interfaces to the routers to create a VPN failover should the above MAN go down.  I use IP SLA to track the MAN, then move to the VPN route when reachability is down.
 
I can source ping from one CISCO router Interface to the other, through the two interfaces to the Sonicwalls and reach the router interface of the CISCO on the other side of the VPN tunnel.      
 
Problem: I can not ping any subnet behind the interface I ping through the Sonicwall VPN tunnel?  
 
Example 2800 G0/2 interface 100.1.1.41 /30 through Sonicwal over Internet to other Sonicwall and out ot the G0/2 100.1.10.41 /30 interface on the other 2800 router.  Ping is fine.

Cisco VPN :: SonicWall / ASA5520 VPN Disconnects

Feb 4, 2009

We have a several SonicWall TZ 190 establishing VPN tunnels with a ASA5520. Pericodically random VPN tunnels will drop and can not re-establish a connection.  In order to re-establish the dropped VPN tunnel, our firewall folks manually drop all VPN tunnels connected to the ASA (they use to physically power cycle the ASA).  They claim this is the only way to resolve the problem and since the SonicWall Life Time seconds for Phase 1 and 2 are set to 28800, they reset the tunnels every 8 hours. Additionally, they claim that SonicWall IPSEC is different that Cisco IPSEC which is the main problem.  Hence they are requesting a SONICWAll VPN concentrator..

DNS Redirect With SonicWall TZ210

Dec 11, 2012

It's been awhile since work has thrown me a curve ball so I was about due. We've got a client that wants us to log into their secure portal, this is normally not a issue. The link they sent us to their 'portal' apparently takes us to the wrong page. Their solution to this is for us to create a DNS entry to resolve that URL to a specific IP address. We don't currently have a DNS server setup in house so I assumed this would be something done on the Sonicwall.

I asked them why I couldn't just go to the IP address instead of the URL anyway and they said it wouldn't work. Is this something that I can maybe create a NAT Policy for and have it redirect traffic to there? I know the SonicWall has a DNS tab but I've never touched it and I'm not sure what I would need to put in there anyway.

So at this point I'm looking for any USB 3g phone card that is known to work.
