I start writing this post telling you that I'm not a qualified network admin, so I beg your pardon if I do not use appropriate terms in my question. Also my english in not so good since I'm Italian and my english in almost scholastic.
This is the "story" :
I bought two switches as described above and actually I have to create 2 VLANS as described below :
VLAN id 2 name "Service_A" ports 1-4
VLAN id 3 name "Service_B" ports 7-9
all other ports can stay in default VLAN1.
my network infrastructure have some other very simple swtiches connected and 1 soho router (static ip 192.168.1.1) with dhcp active and ip pool address released from 192.168.1.100 to 200.
the SG200-26 have static ip 192.168.1.254 and 192.168.1.253
I need VLAN for privacy matter so all computer connected to ports in VLAN2 cannot see nor enumerate PCs and resources on other VLANs,
but I also absolutely NEED that all computer in every ports (and every VLAN even default VLAN1) can access the internet.
I set port 25 and 26 as trunk and all other ports as access. I intented to use 26 as uplink to other switch and 25 to exit to the internet.
Created VLANs but only the VLAN in wich I set 25 as untagged can reach internet.
I asked a Cisco qualified tecnician and give him the switches to work with, but after 2 days of attemptes he said to me that it's not possible
to do what I need.
Please, I desperately need your help, I'm really loosing sleep over this problem!
