Routing to 2 networks from fast ethernet ports of an 857

Hi , I have had a 1720 for some years routing to 2 networks ( one lan 192.168.1.x , one DMZ 203.53.178.x) via 2 ethernet interfaces .

we got an 857 as part of an ADLS 2 upgrade but i don't know who to set up the routing on the fast ethernet ports.

is the above routing possible ?

it seems we are limited to one VLAN ?

can you enter the command :"no switchport" under one interface?

this command let the interface a L3 one, then y can give it an IP address.

No, it does not like the "no switchport" command for a fastethernet port

( C850 -ADVSECURITYK9-M) version 12.4(11)T2

i think you need to change software.

Q. How many 802.1q VLANs can be configured on the built-in 4-port switch (Fast Ethernet 0-3)?

A. A maximum of four VLANs are supported on the Cisco 870 Series with the plus feature set (Advanced IP Services/Advanced Enterprise Services). The Cisco 850 Series only supports one 802.1q VLAN.
