I have a VPN tunnel established between my location in PA and our other
location in Indiana using 2 D-Link 804HV's. The tunnel is established and has
been solid for about a week. The problem is when I attempt to access the
shares on the remote PC's or when performing a RDC. Please keep in mind, that
I had this VPN working perfectly when the 2nd VPN router was at my house
about 10 miles away.
I can view all the shares by typing the IP address into an Explorer address
bar. I can navigate through all the folders and get down to viewing the
individual files. The problem comes when I attempt to do anything with the
files, such as copy them to my PC or view their properties. Sometimes
Explorer locks up and other times I receive a message stating that the
network path is no longer valid. I can then immediately go back to another
explorer window and navigate right back to the PC's shares.
The other problem is that I receive a black screen when attempting a RDC.
Everything I read about this problem points to the MTU value. I performed the
recommended command of
ping ipaddress -l 1500 -n 50 -f
Sometimes everything is fine and other times I receive the message "Packet
needs to be fragmented, but DF sent". I attempted to lower the MTU value in
the D-Link, but the only setting for MTU applies under the WAN menu and
didn't change anything.
I am, however, able to access their VPN router from my location with no
problems.
Running a pathping, I am finding losses at two different places of 100% if I
ping by the WAN address given to the router by the ISP. If I pathping
directly to the PC (192.168.0.56) I don't have any loss. I have contacted
AT&T about line quality problems. They sent out a tech, who apparently placed
a DSL filter on the entire building and was able to get everything
straightened out, but I'm not so sure. (I wasn't there, since I work in the
PA office and the Indiana office is the one with the problem). I wasn't able
to access their router consistently until the tech had finished his work.
Why would I be able to access the router....everytime....but not the PC's
behind the router??
I have also attempted to physically dial down the MTU setting on the NIC
using DRTCP and had no luck.
I tried adding a static route on both sides althought I'm not sure it was
necessary because we are both on the same subnet and have a basic network
setup. Modem -> Router -> Switch. I just found out that I can transfer a
file from my PC to the remote PC in Indiana, but I receive the following
error:
Cannot copy filename: The specified network name is no longer available.
But the file actually transfers????
Can someone help me??? Thanks and sorry for the long post, I just wanted to
