Hi!
After I change my router with a Mikrotik RB760iGS I've a trouble, when I try to do a ping from my computer I recieve a 1ms response time like that I'm trying ping the router, same if I do a trace
How can I fix it?
Already done, no changeHow about to disable your PC firewall for a short period of time and try again?
No I don't, I've that trouble with everything:Show configuration of your router.
I suspect that you have assigned 8.8.8.8 address to interface in your router.

Conf removed
add action=dst-nat chain=dstnat comment=Ping protocol=icmp to-addresses=10.254.254.254
thank you! I noticed that just after my last post, thanks for your help!This NAT rule
grabs just any ping request regardless where it starts and what is its destination and redirects it to 10.254.254.254 (which happens to be one of router's addresses). And similar problem is present on many other DST-NAT rules.Code: Select alladd action=dst-nat chain=dstnat comment=Ping protocol=icmp to-addresses=10.254.254.254
You have to make those NAT rules more picky by including some additional filtering options, such as "dst-address=..." or "<in-interface=WAN interface>" ...
