Hi people, i´m wondering if i need to set statics routes for comunicate two subnets in the same router RB-951G
Here is the thing:
Bridge_work=ether 2 and ether 3 / DHCP server=10.2.3.0/24 /
Bridge_home=wlan1 / DHCP server=10.2.1.0/24
So, my cuestion is : do i need to set static routes for get a good and stable connection between both subnet?
Have you already tried such configuration ? Just asking.
If you have both subnets “terminated” in one router then it knows where both subnets are so it should pass packets from one subnet to the other.
The problem is that devices form subnet 10.2.1.0/24 do not see packets from 10.2.3.0/24 as they are separated by subnets mask /24
You should change mask to cover both nets … /22 should be fine … or make proper masquarading for packets traveling from one subnet to the other.
Using masquarading makes packets from different subnet looks like coming form router so your devices will not see each other directly and e.g. NetBios will not be passed or Bonjur protocol either.
Wait a second…
If you have 2 subnets which are directly attached at the router, then yes, you will get layer 3 communication between the 2 because the router sees these as connected routes.
Static routes are not needed because layer 3 connectivity is there.
The above posts jumps to the conclusion that you need layer 2 protocols to work across subnets, possibly with no layer 2 connectivity between them.
You need to tell us what isn’t working before this can be answered.
Hi guys, thanks for reply.
It was juat a noob question…
Just add 2 rules in firewall filter on the top of the forwards rules:
/ip fi fi
add chain=forward src-address=10.2.3.0/24 dst-address=10.2.1.0/24
add chain=forward src-address=10.2.1.0/24 dst-address=10.2.3.0/24
Nice, that rule could work on VLANs?
I mean: it could communicate two differents vlan?
These are completely unnecessary. You should NOT add them because they don’t do anything that isn’t done already.
Because i don’t know full firewall setup ,let try to set them !
