Hi there,
i have some problem with my network, let's say.. my topology is like this :
Router - Cisco C2960-X (Vlan 1 & 100) - VM Host
> Internet Connected to Vlan1 - and from Vlan1 to Router (port1) : WAN
> VM Host Connected to Vlan100 - and from Vlan100 to Router (port4) : LAN gateway
>>the switch is new, and i only configured security access and VLAN.
i've configured everything in the Router (NAT, firewall, etc) and everything works fine.. until i tried browsing some web with Windows Client. I only using Linux (console/terminal only) as VM host before~
using network Testing tools, the results are like this :
Ping - works, Nslookup - works, Tracert - works, Telnet - works, webBrowser(IE, Firefox,Ms.Edge) - fails (says dns error something)
tried all above to twitter, facebook, cisco, etc.
if i access the web with links(linux command webbrowser), the page(text) loaded. But can't browse using Linux with Desktop env. too.. (debian with firefox browser).
i've asked the Router Support about this too, but it seems like the problem is not from the Router Config.
if i use public IP directly on host and connect it to VLAN1, i can browse with the web browser...
So only from the VLAN100 i can't browse web.
has anyone ever experienced something like this?
is there any way that the switch is filtering/blocking something?
Solved! Go to Solution.

i don't really know what's causing it.. but after reseting all the config and reconfigure the vlan, everything works normally..
anyway.. thanks for all the response~

Can you attach the config from the router and the switch here, please? Remove all sensitive configuration such as passwords etc.

i'm using mikrotik CCR for the router.. and yes, i've configured NAT as well~
u could see from my ScreenShot that i could do everything including tracert, nslookup, ping, telnet to some website.. but i can't access the web with my web browser~
