I've VPN connection set up that i connect to company with. I can connect to all devices (other switches, routers, servers from same subnet with same settings just diffrent ip) but I can't connect to NetGear Router GS748Tv3.

Settings on switch:

  • IP address
  • Subnet mask
  • Default gateway
  • Management VLAN ID: 0 (1 - 4094 or 0) (0 means all VLANs)

Switch has 2 VLAN's configured 1 and 2.

I can access this switch thru VPN if i log in to server and from server to switch but this is a little bit slower then normal way.

Anything I'm missing?


Router in location has IP - and it's only gateway to internet. So far there's no additional network besides Switch has 2 VLAN's but only one VLAN has connected cables to it and network on that VLAN is

I can ping (ip of switch) while being on site but i can't ping/access it thru VPN.

VPN assigns IP's from same subnet as local DHCP does (it's Draytek Vigor 2930 working as DHCP for local network and VPN at same time - so it's all in one device).

  • Need more info about where you are trying to connect from. For instance, if you are in 10.10.10.x/24 and try to reach, you need to create a tunnel between both. The default gateway for switch IP can be different from default gateways for those two vlan's on that netgear box. – RainDoctor May 6 '10 at 1:13

does the switch 'know' how to route traffic to you? [eg does know how to forward packets back to you sitting 'behind' the vpn?].

some manageable devices allow administrative access only from same subnet or only from selected subnets - is your ip ['behind' the vpn] allowed?

  • This is my IP on VPN, Mask, Gateway is empty... I would understand this being the case but why all other managable switches (like Linksys) allow me to log in to them? – MadBoy May 5 '10 at 17:50
  • What is the gateway on your actual LAN connection? Is it also – DanBig May 5 '10 at 18:59
  • @madboy - does your vpn SNATs your connections directly on some local ip? it seems that overlaps with your lan - a picture with addresses, vpn, netmasks, routes would be helpful. – pQd May 5 '10 at 19:45
  • See my update of question – MadBoy May 6 '10 at 10:44
