Hello Kazim,

your post is not clear. Can you post a network diagram of the current setup?

You speak of DSL modem and then you speak of a fiber wan port. This is not clear.

And what do you mean with STC? Is it the name of a provider, of a service or the name of a technology?

Hope to help


Sorry to answer late,   ISP ---- cisco router ---- switch--fiber -- modem

its the diagram as mentioned above.  STC mean Saudi Telecom.  modem huwei or acatel. this modem have a wan port of fiber which is directly connected the cisco switch.

I think the setup you are trying to build will not work,

because you are trying to connect an FTTH modem to a gigabit Ethernet switch.

You will need an OLT switch to make your setup work generally used by service providers..
