I have a Cisco 3750 switch connected to a Cisco 800 router from an ISP provider (I do not have access to this router). I need to provide internet connection to a network through vlan of the same 3750 switch.
The ISP provider has given me a pool ip adress / 29. What I need to do? I have reviewed the NAT option but the 3750 switch does not support it.
yes 3750 do not have NAT, you need find Small router between ISP Router and Your switch for NAT Translation.
Look at small Business routers
unless you can get the provider to accommodate your new vlan/subnet or you introduce a rtr of your own you won’t be able to doing anything unfortunately.
Maybe you can do it with a firewall that running though linux or freebsd, like pfsense or iptables. If you have hability for it.
The original poster tells us that
The ISP provider has given me a pool ip adress / 29
but does not tell us what, if anything, he has done with that pool of addresses. Can the original poster clarify whether he has done anything with that pool of addresses? Is it possible that that pool could be used for the subnet for the vlan that needs Internet access?
