Hi guys,

I have a question about nat. Suppose host A is sending a http packet to 8.8.8.8 from its ip 10.1.1.1 with source port 45000.
The router that does the Nat sees the following
source:10.1.1.1:45000 ---- dest: 8.8.8.8:80
and it proceeds to nating the ip and lets assume that the source port chosen by the host is already taken. So router will assign another free port to the host nat.
NAT entry
source: 123.12.23.1:5555 ----dest: 8.8.8.8:80.
My question is, what happens when the response comes back and the router needs to send the packet back to the host. Will the router preserve the port number that the host choose initially i.e. 45000 and use that port along with the private ip of the host and forward the packet to the host or will the router use the same port it used for nat  or other random ones.

Kind regards

Hi All

I'd like your help with a static route config?please see below i this right

Belfast)conft#ip route 10.203.0.0 0.0.255.255

thank you all

Please see the diagram

I have the main router which holds the VLANS configuration (MAIN and GUEST) , two access point connected to it, and it works fine.

In the next location I don't know what I need to do in order to accomplish the following :

The Access point will show the two networks (MAIN and GUEST) , and the pc which is wired will be only on the guest network.

How do I accomplish that?

My 10yr old Netgear WNR3500 seems too old and only giving up to 10Mb with our new equipment.  
Its RangeMax wireless-N Gigabit router.  Been good for us but.. for the last few years with newest devices seems compatibility issues there.

Should we stay with Netgear and get the latest model or some other good options around there?
Thanks.

I a private school's IT services.  They have three campuses in three different towns however all three have very similar infrastructure.  They have the same SonicWall NSA2600, Dell Enterprise Switches, and separate VLANs for Faculty, Students, Guest and Security cameras.  

The issue that I am having is when a classroom is assigned a project or task the requires the entire class to use their computers to access a single resource on the Internet.  I have a few examples with this but it doesn't seem to matter what the website is.  The first ten or so students to request the website will be able to resolve the web address and load the web page.  The remainder will end up with a connection timeout error trying to load the page.  And if those 10 or so who did load the page, if they hit refresh will get the same error as the rest.  If there is a break in the request to the page for about a minute it will load again.

They have a website hosted by GoDaddy and I have even contacted them to see if we were triggering any alarms or peaking any resources and they confirmed that we are not nor would they expect us to be with the account we have selected with them.  The error on the web browser "Connection Timeout Error"also does not coincide with  what would be witnessed had it been some kind of flood protection with them.

I have contacted SonicWall support and we have recreated the scenario at all three schools and review configurations on all three SonicWall devices to rule out …

Hello,

If I want to override the current EIGRP defaul route, how can I do that? Do I just create a static and redistribute into EIGRP or is there more to it?

For ex.

Switch#sh ip route
Gateway of last resort is 10.255.254.5 to network 0.0.0.0

D*EX  0.0.0.0/0 [170/3072] via 10.255.254.5, 7w0d, Vlan101

Select all Open in new window

and  I want to default route to be 10.255.254.10 fo example.

Thanks

Devices:
Google Home,
Aruba IAP-305 (RW)
NordVPN


I am trying to set up a VPN for my Google Home so it will register as being in the US. I am currently in Ireland and have purchased a subscription to NordVPN.  From what I understand, a VPN cannot be put on the actual Google Home device.

I currently make a lot of calls to the US. Google Home offers free calls in the US but is not available here in Ireland. This is one of the main things I want to get from my Google Home.

If the net result of the VPN makes Google Home look like its in the US, I do not want the rest of my tech devices to think they are in that location, i.e all of my other tech devices have locations in Ireland.

hi folks

i am wondering if anyone ever used Cisco WRVS4400N's port mirroring feature to monitor traffic of a given port?

i have tried any individual port or even all ports together as the source, but i still cannot see any mirrored traffic from listening to the specific port (Port 4), as shown below.


i have no idea why the device doesn't work as expected. do you have any suggestion please?

regards,

Have a environment where I want to restrict internet to all computers except of 2.
Looking for a router that instead of blocking the once I want to restrict I should be able to block all and allow the the few I want to allow (a ip range)
Not a big network no fancy router simple
it's about 25 devices all have a static ip configured on the device

Google Photo's "Backup & Sync" tool is making my internet connection unusable when I'm uploading photos from my desktop.  I have another desktop & laptop, all on the same WiFi.

I do see I can limit upload and download speed.

QUESTION:

If the desktop is the only device requesting bandwidth, I presume that would get all of the bandwidth.

However, when I start using my laptop, shouldn't it share the connection and play nice?

My Comcast is normally 30 Mbps down and 5 Mbps up when I'm not uploading.

When uploading without specifying a limit, it can drop to under 1 download and 1 upload.

I just specified a limit of 400 KB/sec and download limit to 1800 KB/sec to see if that helps.

Thx
Mike

Hi Expert, Please see the attached screenshot. I am installing Solarwinds. but I got an error message. I do not know what SQL server name is to fill the SQL server name. I tried different name including the computer name. During the process of installation, I follow the steps to install, which include automatic SQL installation. Did I miss some step or wrong? Thank you
