Can't Access Some Local IP Addresses on VPN

Running OS X.4.8 Server, and connecting to the VPN from OS X.6.4
I've had a problem for a while in which when I am connected to the VPN from "outside" the router, I cannot connect to or ping certain machines, although I have no problem with others. Pressed for time, I worked around this by just setting up port forwarding on the router and connecting to the machine directly.
Today I noticed that I cannot connect to some machines that I COULD connect to last week! I am not aware of any changes to any of the machines involved that would explain this.
What is the best way to diagnose and resolve this issue?
Turning off the firewall on the server does not alleviate this problem.
Thanks for any advice.

All IP addresses on the LAN served up by the VPN should be coming out of the 192.168.1.xxx pool.
That causes problems with the typical subnet use for most coffee shops and home networks on the planet; that's a very common subnet for folks to use, and having the same subnet in use on both ends of the VPN will cause IP routing problems.
It's common practice to use a subnet further up the 192.168.0.0/16 block, or a subnet somewhere within 10.0.0.0/8 or somewhere within 172.16.0.0/12; in the other private blocks. (If you should lack sufficient public static IP addresses for your needs, obviously.)
Curious -- I can't reconfigure the LAN in any kind've reasonable time period but what if I change my local (home) IP address range? Do you think that will clear up the problem?
Thanks,

Can't access some websites and speed problem

Hi guys,
I hope to find some help here please as I am desperate!
It has been a week now that I am having problems with my broadband, suddenly I can't access some italian's websites (which I was able to access before). The browser tries to load up the page but nothing happens (it doesn't even give me an error). I tried those website on both my laptops (one windows and one mac) and on 3 different browsers but I have the same problem.
I even tried to use Google DNS on my mac but that didn't solve the problem, I have already tried to reset my BT home hub but again that didn't help.
Any ideas?
The other thing is that my broadband speed is really strange, because before it used to be very fast during the day (500-600 kb/s download) and really slow during peak-hours (which I know is normal). But for the past month it has been really slow (70kb/s download) even during the day, it has some brief moments when it's slightly faster but not as fast as before. Any suggestions on what would be the problem or what I can try?
I will really appreciate your help.
Thank you all
Robbie

Can't access some sites when using Aiport Express, why?

I'm using Windows 7 and my router is a wireless Apple Airport Express that is approximately two years old. Suddenly I can't access some sites (for example www.sthlm.friskissvettis.se, or www.vegetarian-shoes.co.uk, some streamed tv-shows on svtplay.se, and a number of other random sites) when connecting to internet with my router. It worked good until recently and I'm fairly sure this problem emerged when my ISP upgraded from 10/10mbit to 100/10mbit speed. Most other sites like facebook and google works fine.
When using my network cable to connect to internet everything works fine and I can access these sites.
Firmware is current and I've tried reseting the router to factory defaults.
Tried different browsers, and I can't ping the "blocked" sites either. Tracert www.sthlm.friskissvettis.se starts with 10.0.0.1 and continues through a number of long addresses until it says timeout. The last working address before timeout was sth-tcy-ipcore01-ge-0-2-0.neq.dgcsystems.net [83.241.252.13], if it matters. Tracert www.vegetarian-shoes.co.uk also eventually gives me a timeout.
When the network cable is plugged in, I still get timeout on tracert www.sthlm.friskissvettis.se even though I can access the site in Chrome. Weird. www.vegetarian-shoes.co.uk doesn't give me a tracert timeout when the cable is plugged in, and I can access the site as usual.
I've tried changing DNS servers to use opendns servers instead, but to no use.
I've tried pinging these two sites with a lower MTU packet size (with this method: http://www.richard-slater.co.uk/archives/2009/10/23/change-your-mtu-under-vista- or-windows-7/), but still can't access them through ping...
I don't know what to do anymore.... any suggestions???
Thanks

Hi Punice
first try to disable JavaScript from : Firefox button (or Tools menu) > Options > Content panel > '''UNcheck''' Enable JavaScript.
if the above does not help check with a few malware/virus scan programs for virus. You need to use all programs because each detects different malware. Make sure to update each program to get the latest version before doing a scan.

Can't access some secure sites through proxy?

can't access some secure sites through proxy server on osx it just keeps going local authority couldn't be contacted, i had the same problem with parental controls, but now that is off and its still doing it, is there a setting or something i need to enable?

In my original post, not today's, I had said I was having the issues on the Mini, running OSX 10.6.8 and Safari v.5.1.5 for my bank's pill pay. I should have been more specific as to which machine and OSX Safari browser I'm having the T-Mobile problem with. My mistake.
It is on both the MacMini and now the Air too. A moment ago, I was able to log in to my.t-mobile.com on the Air, but after putting into my Bookmarks folder, I can't do it anymore. The Log in button comes up greyed out instead of green.
I'm also still having trouble with my bank's bill pay section on both computers too.
I wonder if it's related to the saving of the log in info or putting in the Bookmark Folder?

I'm an admin of this site, but now can't access some pages in Project Server 2013 e.g. Project center, PWA setting

Can't access some websites using time capsule

Everything has been working just fine with my time capsule and my imac and just today I couldn't access some websites for some reason. I tried many other sites including this one and can get to them no problem. I have been through all of the airport settings and trouble shooting and can't find any problems, also the other 2 computers and my blackberry can't access some of the same sites either, I am stumped. Does anyone out there have any idea whats going on? Thanks for your help!

Welcome to the discussions!
Suggest that you contact your ISP. It sounds like their DNS server is overloaded at the moment, but also unlikely that they will ever admit it.
It wouldn't hurt to power cycle your complete network as well. Just power everything down, order is not important.
Start the modem first and let it run a few minutes by itself.
Then start the next device connected to the modem, probably your Time Capsule, and let it run a few minutes.
Then start your computers and devices one by one the same way.

Can't access some shared files

I have a computer here where the user can't access some shared files. From the machine she normally uses, the folders are greyed out. I've checked all the permissions, and everything is in order. She was even able to access the folder from a different Mac. The mac is fully patched, running OS 10.6.8.

More Info:
After trying multiple things, I have more info to solve the problem. 2 other computers (one is another iBook and the other is a PC) in the house, access the hard drive as advertised with no problems. The only thing that has changed on my computer recently is the replacement of a 1G iPhone with an iPhone 3Gs. This phone did some weird things when syncing, specifically with our photo programs. It locked up Nikon transfer and iPhoto was working strangely. I felt the best way to alleviate those 2 problems was to shut down my computer, and restart. This is when I encountered the problem with accessing the TC. Things are also a little bit more complicated because I use the TC as the storage medium for both iTunes Library and iPhoto Library, both of which I can't access given the current problem.

I can't access some of my songs on iTunes with my Sonos wireless player.

I can't access some of my songs on iTunes with my Sonos wireless player. Sonos help says this is due to propriatary rules from iTunes that were eliminated after 2009 and there may be some upgrade possible, but iTunes is singularly unhelpful finding anything related to this issue.

pls. help.
The pop up error msg. is "Sorry, you don't have access to this page"

Hi,
According to your description, after you cleared job queue about force check-in then you can't access some pages in PWA.
Maybe you need to check in the pages which has been checked out.
If you have administrative rights, it is possible to override the check-out via the View All Site Content page:
Site Actions->View All Site Content->Pages->Hover the item you want to check in, and from the context-menu (arrow-down next to the filename), choose "Discard Check Out"
Besides, to troubleshooting the error “Sorry, you don't have access to this page”, refer to the following articles:

I enrolled in weight watchers online only to find out that I can't access some of the tools I need because I need adobe flash player is there anything I can do. I've already paid for the service!!!!

Send a stiff email to Weight Watchers to suggest they need to remove their software videos from the FAT and BLOATED Flash container and trim down to HTML5 in the future if they want to stay on program.
In the mean time you are going to have to employ work arrounds with your iPad.
Try the Skyfire browser app, This can convert some flash content remotely into a viewable format playable by Quicktime on your iPad.
Its not however guaranteed to work on DRM protected material and its very likely these Weight Watchers videos are so protected I am afraid to say.
Other apps such as iSwiffer attempt streaming of flash but are slowed due to band width.
You could also use a VNC type app such a Splashtop to stream direct from your PC to your IPad however sound is not guarranted to work with these apps.
Finally the most satisfactory solution at the moment plunk yourself down in front of a PC/Mac or Linux box and watch the flash their.
