Sorry, but you are not providing enough information to help.
Which ping test are you using and exactly what result do you get?
If you are using the ping www.microsoft.com, does the name show a resolution correctly and not respond or does the name show that DNS does not resolve?
Which device are you running the ping on, the computer behind the firewall or the firewall itself?
When the ping does not work also run a traceroute to the same address as an additional test.
Your configuration does show there are default routes configured instead of one. Is the default route active?
show route 0.0.0.0/0 exact
Delete the one not in use which appears to be the 192.168.2.1 from your config
routing-options {
static {
route 0.0.0.0/0 next-hop [ 192.168.2.1 93.51.230.129 ];
}
}
