Your ip address is 10.7.69.12 The time is 11/17/2009 10:38:40 Your reported hostname is 'host10-7-69-12.vpn.udel.edu'
This is your
10.7 private UD address. It is possible
your UDelNet ID is assigned to a group that gets
a subset of the total pool of allowed
IP numbers. It is also possible that your IP number is statically
defined so you always get the same IP number.
The reason for these special assignments is to allow UD server
administers the ability to allow you or a small group UDdelNet users
access, while denying access to all others. To make this work the
server administor needs to know the IP numbers which are reserved
(see VPN for UD Server Administrators.)
VPN allows trusted access through untrusted wide area networks. That is, a user with UdelNet account and our UD VPN client can connect to UDelNet and be assigned a UD private address. All traffic is encrypted and thus safe from snooping on the untrusted network. However, it is important that all networks relay the packets from the VPN client to our VPN server. In particular UDP ports 4500 and port 10000 must be open in all firewalls.
With these ports blocked you may get a message such as
contacting security gateway at 184.108.40.206 ...with no connection made. If you are at an internet public site, there is not much you can do about their firewall configuration. Some hotels offer internet service upgrades to allow VPN. If you are visiting at another university you should bring this to the attention of their help desk. http://www.udel.edu/ip, and record the IP number and the time stamp. Normally the IP number should be a number assigned to your ISP, however when connected using the UD VPN client the ip number should begin with
10.7. If this is not the case, report the problem to the help desk with the incorrect IP number and time stamp.
ping 220.127.116.11 ping vpn.nss.udel.eduIf the second one doesn't work, then you have a
dnsproblem. Either fix the
dnsproblem or reconfigure your VPN client and use
Split Tunneling permits traffic destined outside the tunnel to proceed to your ISP's gateway while all traffic destined for addresses inside the tunnel to proceed through the tunnel. Without it you would only be able to access destination inside the tunnel.
After connecting to the UD VPN server, try to connect to a non-UD site. This
should work, just as if you were not using VPN. Hosts inside of UDelNet should see
you coming in with a
10.7 IP number, while all other hosts should
see you using a globally unique IP number from your ISP.
note: Currently the UD VPN server considers IP numbers
128.4 as inside
the tunnel, but the routers in the EE CIS network, which assigns the
IP numbers, will not route the private
addresses. This means split tunneling will not work going to hosts in the EE CIS network, and
it means EE CIS servers can not be configured to allow UD VPN connections.
10.7. These are conflicting tasks, and they will not work together. See VPN and Proxy servers for a detailed description for using both from home.
