SOURCE: Need to network SG300 Firewall and Qwest (Motorola) 3347-02 Modem

The modem needed to be set to a 192.168.x.x network, and the SG300 Firewall WAN port needed to be set to a dummy IP on the same network for it's IP, and the specific 192.168.x.x address for the gateway and DNS.

Bad ADSL modem at your ISP's end?
Deteriorated twisted-pair wires from the telephone-pole to the demarcation box on the outside of your home?
Dying ADSL modem inside your home?

First, try a different ADSL modem.
Then, call your Internet Service Provider, and get them to trouble-shoot.
Finally, switch to a cable-modem provider.

How to connect my MSSQL server through VPN by using PPTP


192.168.1.X is a local ip address ,, i trust that thhe vpn is in seperate places and is done with the wan ip over an internet connection?????

OK maybe the problem isnt on your side but the main office building,, when connecting , have someone looked for repeated attemps to connect by observing the fire wall,, if it appears to be blocked byu the firewall simply diasable any and try it out.. If it works then all you need to do is set the firewall correctly..

I was reading the ip address in your original post and those are local address,s are you certin the VPN is correct ???? did you use the correct STATIC IP ADDRESS ASSIGNED BY YOUR ISP??

Speed test through the modem gives proper results. Connect a Fortinet 110c IPsec VPN and speed is tremendously slow


VPN connections are encrypted, this adds extra overhead to the connection and an extra place all data must route through.
Once connected to a VPN your speed is determined by the slowest connection between you and your end point (The site you're visiting, or the service you are using)
For example:
If your home / business connection is a 20mb but your VPN is a 1MB connection, then your speed is going to be less then 1mb once you connect through the VPN.

Encrypted traffic is usually a bit slower, however if you feel speeds are far slower then they should be, you will need to contact the vpn service provider and see if any settings in your VPN software can be changed to speed things up.

Hello. It appears my router is blocking VPN access to the office server. I can connect using the ethernet cable so have isolated the problem to the router firewall. How do I get around this? Thanks


Hi
I will make a couple of assumptions on you setup. First, you have some type of highspeed internet. You have a retail type router/firewall plugged into your internet modem. You are using a VPN Client software installed on a PC or Laptop. By stating that when you connected using your Ethernet cable, you were plugged directly into the Internet modem.

Basically, what you have here is a configuration issue with your Router/Firewall. I use the Cisco VPN Client Software from home. This software uses UDP over TCP port 10000. Your VPN Client will use something along this line as well. So, you need to do one of two things here. Determine what Protocol and Port your VPN software uses. Login into you Router/Firewall and add that to your outbound allowed traffic. Or login into your Router/Firewall and configure it to allow all outbound traffic.

If you are not sure how to do this, the documentation that came with your Router should contain a Tech Support number to call. They can walk you through this in short order. Otherwise, post your EXACT make and model of your Router/Firewall and I will try to get the information for you.

Hope this helps.

Cable modem connection keeps repeating checking and then down over and over, tried a different router works fine, tried a different modem same issue


I had a similar problem a while back when I bought a new cable modem. I didn't realise that my cable provider needed to have the serial number of my cable modem configured on their system.

I ended up calling them to ask them about the problem.

There is no way I could have solved it without calling them.

I think it is to do with stopping unauthorised users from connecting to the cable.

I remember they wanted my name, age and grandma's inside leg measurement before they would help me.

So if you have nothing to hide just give them a ring and make them help you. This is what you pay them for after all.

:)

Can tlog in sg300 using a satellite remote access


Accessing a VPN through a BGAN should be fairly simple. It sounds like some of the settings for the VPN might have changed. If you changed any settings on your computer, or if you have added any type of security settings or firewall. If you need any assistance with your BGAN let us know. We do sales of Satellite internet terminals such as Thrane & Thrane, Wideye Sabre, Hughes, Fleet Broadband, and much more. We also do repair of Broadband satellite terminals. You can visit our website at www.BlueCosmo.com, or call us at 877-258-3496.bcrepairs.png

How do I connect my cable/DSL line to this device?


The 3Com® OfficeConnect® Cable/DSL Gateway does not have an internal cable or DSL modem. The gateway router is designed to connect to the Ethernet output from your cable or DSL modem. An Ethernet cable is supplied with the product for this purpose.
