I'm unable to ping my ER605 v2.0 after changing those settings:

- [Deactivated] Network Security -> Attack Defence -> Block Ping from WAN

- [Activated] Network Security -> Firewall -> Broadcast Ping

- [Activated] Network Security -> Firewall -> Receive Redirects

- [Activated] Network Security -> Firewall -> Send Redirects

- [Activated] Network Security -> Firewall -> SYN Cookies

My ISP router is set to Bridge mode and connects ER605 v2.0 directly to the WAN port. The WAN on the ER605 v2.0 is configured with a "PPPoE" connection.

Doing a traceroute shows me I'm directly connected to my ISP from my ER605:

$ traceroute 8.8.8.8

traceroute to 8.8.8.8 (8.8.8.8), 64 hops max, 52 byte packets

I also tried creating a NAT rule to reach one of my devices via ssh but when I try to connect to it through the internet I get a timeout. It's as if every external connection is forbidden.

What am I missing?
