How to set up vpn on tilgin modem - Computers & Internet

This is a known issue with that modem and Comcast wont support VPN from residential installations. If you want to change modems that don't have this issue, get a Motorola surfboard. If you want to change settings on the one that you have because of the protocols for assignment of addresses let me know

Contact your DSL Service provider. Only they will be able to give you the correct VPN settings.

Either your web-browser has "cached" the web-page previously delivered by the TILGIN,
or your computer is still connected to the TILGIN.

In the former case, "reload" the web-page.
In the latter case, turn off the TILGIN router, and try again to connect to the ZYXEL router.
Also, check that your network-cables are correctly connected to one of the LAN ports on the ZYXEL router.

check that the VPN setting at the office allows NAT TRAVERSAL

Most modem/routers don't support two vpn tunnels at the same time.

Check this out as there are also support details if you would like to check further!

hi, mate check firewall settings of your modem/router. Then contact your IT administrator and he should be able to make changes to configurations for you. In most cases if server classify's your connection as unsafe it rejects it.

If that is the case you may forward ports on the router for VPN connection, try to open 47, 500 and 1723 all TCP and UDP protocol.

Here's what you need to do, check the IP address of the computer where you have the VPN software,

here's how:
click start> run> type cmd> hit okay
on the black screen put in ipconfig and check the IP address there,

> when you get the IP address then we can enable port forwarding on the router

> open IE on the working computer on the address bar, type 192.168.1.1

> nothing for username and password is admin in lower case

> then click on the applications and gaming tab on the router,

> and from there, example of how to field that in is like this,

> for aaplication name - VPN1
> for port it is 47 to 47
> for protocol it is BOTH
> for IP address ex. 192.168.1.XX - 192.168.1.100
> then check enable, do the same thing for the rest of the port.
> save the settings and try it again after.

> if it is still nothing, you may connect the computer that has the VPN connection directly to the modem and check if you will be able to connect via VPN

i'll wait for your response, thank you and have a nice day!

Two routers on two different sets of internal IP addresses will cause all kinds of conflicts. A VPN router is even worse. VPNs (virtual private networks) are designed to create encrypted tunnels between two computers. The computer its set to connect to must be authorized either as a user or a device with proper credentials. If your VPN authorizes devices based on MAC addresses, then unless your router's MAC address was previously authorized, youre not going to connect. Lets take the router out of the equation for a second. Do you have a working broadband connection from the sonicwall that the router can be plugged into? If you do, then you can treat this connection to your router like its a cable modem or DSL. If this connection has manual settings (such as IP address, default gateway, and primary and secondary DNS addresses) you will need these settings too. Post back and keep us updated...

Hi,
Please see the specicification, also check with you company
IT Admin, to release it to the Max speed or to check the
net work cable, may be too long, also Test the cable with a Data Test meter and conform the data quality. Or change the port from main router.
Otherwise change the whole networking router.

Regards

login to the router and check these things
