Hello.
My previous configuration was TP-LINK TL-SG2216 → fiber → Cisco SG200.
TP-link switch sends VLAN trunk with 2 VLANS on the fiber port and Cisco had some ports which had untagged access to these vlans.
The cisco switch was burnt by the storm and was replaced with RB250GS.
And now there’s a problem. Everything seems to work fine. Pings are responding correctly. But there is problem with accessing to any web page.
I noticed that RB250GS is not passing any packet larger than 1492 bytes. Just like it was filtering packets with vlan tag.
Changing MTU to smaller value fixes this problem, but it’s not a solution.
Is my RB250 damaged or it’s a “feature”?
Or maybe it’s not working well with that TP-link?
Regards
