Re: Problem with DHCP

have you added default route in switch directed to adsl router? also 3 static routes which destined to VLANs at adsl router. also check for packet drops or errors in connected interface

Re: Problem with DHCP

I send you what I did, in the configuration, concerning the losses I started to have as soon as I changed the mask of the Modem ADSL in 26

I put the cable that connects my cisco switch and the ADSL Modem in ports N ° 1

Re: Problem with DHCP

in switch, add below route.
destination - 0.0.0.0
subnet - 0.0.0.0
next hop - 192.168.1.1
after that user traffic will move in to adsl router and return back for VLANs

Re: Problem with DHCP

that is bit strange. if default route and internal routes are added it should be able to access internet. can you try traceroute and check where is it getting dropped?

Re: Problem with DHCP

I do not think it's a DNS problem, because from VLAN 10 I do not have a problem
from VLAN 20,30,40 I can go to the external address of the Modem but I do not go out anymore it's like my vlan addresses are not routable
for the DNS I use 8.8.8.8 I even used other DNS of the operator who walk but without success
