ISP and two routers -> switch. Safe?

Hi!

I have a network configuration which has two routers and an ISP modem connected to a Gigabit switch. Both routers get two (static) public IPs and work fine. Everything works just nice - so far.

So my question is: am I going to face any problems (like some kind of interference) with this configuration and is it safe (since the users of the other router cannot, or more like MUST not, have access to the network of the other router)?

If this configuration isn't right, please give me some advice to make it better. The importance is just having two different public IPs and separate routers (networks), meaning they shouldn't be directly connected to each other.

Thank you!

Hi,

As long as you have no routes on the routers to other router subnet then computers won't be able to see each others.

Since they are in separate vlans in outside switch and routers not connected then no issue with it
