Need help about VPN and WRVS4400N and WRT350N

Hi,
I wanted to know if I can set up a server on in my house so people can access it from the internet? and for that would i need a WRVS4400N router or is the WRT350N router enough for it?because i was reading about the VPN option in the WRVS4400N router. Thanks for looking and all the help.

Which people? VPN is a good option if you need secure access for a small group of known people to the server. For a public, general access server it is of no benefit, though. Any router would do there.
But I generally only recommend to run servers like ftp servers to people you know something about networking, computer administration, security, etc. If you run an open server in the internet it can be accessed (and will be accessed) by all kinds of people. It is your responsibility to maintain an up-to-date and well secured system that prevents other people of abusing the server. It is also your responsibility to monitor the server for indication of abuse and immediately take actions if you find that there was an intrusion. You can read the stories in the internet of people which rather naive run a server open in the internet and had to deal with the police after their computer had been used to spread illegal materials.
Most people are just happy when they manage to get it working somehow and forget that once the server is up and running the real work has just begun...

I need help integrating Microsoft Office, Outlook and Calendar with my job and is it possible

Ok guys I am new to the iphone 4s. I just dumped my Blackberry after 10 years. I need help integrating Microsoft Office, Outlook and Calendar with my job and is it possible? Also I need it to automatically push email and appointments to my phone? I will buy any app just need to know which is best for work environment. Here is what I am thinking about doing. http://www.groovypost.com/howto/apple/sync-iphone-or-ipod-touch-calendar-and-con tacts-with-google/ Is this the best way? For personal use I am using paid G whiz app

I use Google Calendar Sync to sync my work Outlook calendar to a gmail account, then sync that to my iPhone. It works well for me for the past couple of years.
As far as mail itself, just ask your it folks for settings for remote access to your exchange account, and then set it up on the phone.
As far as working with Office docs, to be able to actually edit them and such, look in the app store for DocsToGo or QuickOffice - they both are good but each has it's pros and cons, so on balance it's down to mere preference i think.

TS4268 I need help getting my face time and imessage to work.

I need help getting my face time and imessage to work. It is saying wating for activation. I just got my iphone 5 2 days ago. I have reset it from the phone and from itunes on the computer, made sure I'm attached to wifi.

The 3 basic troubleshooting steps are these in order: 1. Restart your iphone 2. Reset your settings/iphone 3. Restore your iphone. Since your iphone is only a couple of days old, you should backup your device before restoring. If you don't have anything on your iphone that you care to lose, then simply restoring without a backup is fine. A quick reset of pressing the sleep/wake button (top of iphone) and your home button simultaneously and holding it until the silver Apple logo appears.

Need help about ref cursor using like table

Hi Guys...
I am devloping package function And i need help about cursor
One of my function return sys_refcursor. And the return cursor need to be
join another table in database . I don't have to fetch all rows in cursor
All i need to join ref cursor and another table in sql clause
like below
select a.aa , b.cc form ( ref_cursor ) A, table B
where A.dd = B.dd
I appeciate it in advance

My understanding is that you have a function that returns a refcursor and is called by a java app.
Because this is a commonly used bit of code, you also want to reuse this cursor in other bits of sql and so you want to include it like table in a bit of sql and join that refcursor to other tables.
It's not as easy as you might hope but you can probably achieve this with pipelined functions.
Is it a direction that code should be going down? yes, eventually. I like the idea of pulling commonly used bits of code into a SQL statement especially into the WITH section, provided it could be used efficiently by the CBO.
Is it worth the effort given what you have to do currently to implement it? possibly not.
what else could you do? construct the sql statement independently of the thing that used it and reuse that sql statement rather than the refcursor it returns?

Need help about 1015

need help about 1015 it says connect iphone to itunes on screen i did it but it doesnt work and says unexpected 1015

Try restoring it: Make sure you are following the instructions in this procedure to the letter. Here they are, with emphasis on some easily overlooked requirements:
Disconnect the USB cable from the iPhone, but leave the other end of the cable connected to your computer's USB port.
Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.If you cannot turn off the device using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the device turns off, release only the Sleep/Wake button.
Continue pressing and holding the Home button while you reconnect the USB cable to the device. The device should turn on.
Note: If you see the "low battery" screen, let the device charge for at least ten minutes to ensure that the battery has some charge, and then start with step 2 again.
Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears (iTunes icon and USB connector) release the Home button.
If necessary, open iTunes. You should see the "recovery mode" alert ("iTunes has detected a phone in recovery mode").
Use iTunes to restore the device.
If you do not see the "Connect to iTunes" screen, try these steps again.
If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
If you have backed up the iPhone in the past, select the device in iTunes and choose "restore from backup".

I need help configuring three products: WRVS4400N, WAG325N and WVC200

Hello,
I want your help in three linksys products as mentioned below:
WAG325N ADSL2+ Router
WVC200 PTZ CAMERA
WRVS4400N VPN Router
The computer connections and configuration of above linksys products which I am working with and which are connected with the above three linksys products at present are as follows:
1) I have one server and one laptop.
2) Laptop has two wireless adapters which I use to connect to the routers.
3) The server is connected to the WRVS4400N Router through one of the four ethernet ports mentioned on backside of the WRVS4400N Router. The DHCP of this router is disabled by me and the router's default IP 192.168.1.1 was changed to 192.168.1.12
4) The WRVS4400N router is connected to the Wag325N router for internet access to the server and server is connected to WRVS4400N Router as mentioned in point number 3 above.
5) The WAG325N router is setup as per the instructions mentioned that came with the CD of this router. The only change that I have modified is the router's default IP. I have changed the default IP of WAG325N from 192.168.1.1 to 192.168.1.13 and DHCP is enabled on this router.
The help that I want is step by step as follows:
1) I want to configure the both routers in such a way so that I can access them from anywhere across the world i.e. remotely using internet.
2) I have WVC200 Camera which I setup according to instructions mentioned in the CD and also configured the DDNS service. But when the " RJ45 Cable is connected " to my WAG325N router and Camera, then only the camera works properly. What I want is that after the setup is completed, I want to remove the RJ45 Cable connected from my camera to router and use the camera wirelessly from any location within the range of my above mentioned WAG325N router. I need flexibility to use my camera without cable connections from any location and any rooms of my house. I also configured the port forwarding and DDNS properly. The only problem is that if I remove the Cable after the setup of camera is finished, then the camera access is not working on LAN or internet(through DDNS). Whereas the same works on LAN and internet using the DDNS service, when the cable is physically connected to the WAG325N router. Also I want one more thing additionally other then this. I want to use this camera wirelessly by configuring the port forwarding options on both routers at a same time(i.e. simultaneously at once on WRVS4400N and WAG325N).
3) Now as two DHCP cannot work at a same time and as my routers are connected with each other, So I have disabled the DHCP on WRVS4400N. Here I need help so that DHCP can be enabled on both at a same time. Because if the DHCP is not enabled on WRVS4400N then I have to give IP to the server which is connected with server. If I enable the DHCP then there are two DHCP's at a same time on same network and thus problems occurs in internet access to the server. So, what should I do in such a way so that I do not have to give any IP to my server and set it to automatic.
4) This question is just for my knowledge so that I can use the above mentioned linksys purchases upto full extent possible in future. I want to know what is VPN and how is it usefull? What is the difference between VPN and VPN tunnel? How can VPN be used to access all my network resources connected with my server in the above situation where my server is connected to WRVS4400N which in turn is connected to WAG325N?
Thanks !
Sincerely
Kalpesh Sharma

for question number 1:
you said that your main router is WAG325N, for you to remotely access the 2nd router is for you to forward the IP addr [192.168.1.12] on your first router and change its management port of your second router that is located on either the security tab or the administration tab on its User Interface
to access your first router open and Internet Explorer and enter
http://[public IP addr]:[management port]
the PUBLIC IP or INTERNET IP is located on the status page of your router
to access your second router just change the management port to
ex.
http://66.77.88.99:8080 first router
http://66.77.88.99:8081 second router
for question number 2:
make sure that you have configured all wireless settings on both your camera and your main router WAG235N, once done save settings and power down your camera and power it back up.
for question number 3:
for you to enable DHCP on both routers your connection can go like so...
from a regular port of your main router going to the INTERNET port of your second router [this way you can enable DHCP on both routers]. INTERNET is no problem, your cesond router will be able to get connection
for question number 4:
VPN - Virtual Private Network
VPN tunnel -is/are connections from router to router [gateway to gateway]
VPN is used to connect a diff network on a diff location for you to have access to the shared filed [it is like a file sharing through the internet]
for you to be able to use VPN tunnel you have to connect to a different VPN router on a diff location. In that way you can get access to the other network
