+BudMan MVC Posted October 28, 2008 MVC Share Posted October 28, 2008 And what device is going to do your NAT from your public IP 85.. to your private.. I was not aware the 3com 4500 "switch" supported NAT. Intelligent and secure Voice-Ready edge connectivity The 3Com? Switch 4500 family of managed, stackable/clusterable 10/100 and 10/100/1000 Ethernet switches provides secure, flexibleLAN connectivity> and advanced voice-optimized features such as Power over Ethernet (PoE) and auto-voice VLAN and QoS. Gigabit models also offer optional 10-Gigabit uplinks via local connection modules or XFP transceivers. Just because a device will do routing/vlans, does not mean it supports NAT.. Which sure looks like what you need since you mention those private addresses, and since your on 30bit mask.. there are only 2 hosts on that segment.. Yours your and your ISPs, so you going to have to NAT to allow more devices to use that internet connection. That is not a border type device. Its a lan switch -- If you going to connect your network to the Public net you need a router. Maybe there is a Network Address Translation module for that switch -- but I was not aware of it. And a quick breeze through the manual makes no mention of being able to do NAT that I saw. Link to comment Share on other sites More sharing options...
slack_guru Posted September 27, 2010 Share Posted September 27, 2010 hi, i'm trying to broadband a internet connection through my 3com 4500 switch but not reaching. situation: internet adsl router, my computer nic card must have ip 200.161.131.72 and gateway 200.161.131.65 for internet connection. can i plug the internet router directly to 3com switch to broadband connection ? i've tried this, put 200.161.131.72 for switch ip address; 200.161.131.65 and my internal lan 200.161.131.0 in the switch static routing table and nothing happens what would be the appropriate configuration for this situation ? thanks Link to comment Share on other sites More sharing options...
+BudMan MVC Posted September 27, 2010 MVC Share Posted September 27, 2010 Well you would not put your nic IP on the switch, that is for damn sure ;) Just use the thing as a dumb switch and you should work fine.... Link to comment Share on other sites More sharing options...
