Hey guys,
Just got a new RB2011uis, upgraded it to 6.18 for a small biz
I am guessing the NAT alone is not enough, I need to setup firewall rules:
My current setup (dont mind the time, ntp was added router is just not on the net):
[admin@MikroTik] /ip firewall> export
jan/02/1970 05:30:01 by RouterOS 6.18
software id = ILFZ-7XCP
/ip firewall address-list
add address=192.168.100.0/24 list=support
/ip firewall filter
add chain=input comment="default configuration" protocol=icmp
add chain=input comment="default configuration" connection-state=established
add chain=input comment="default configuration" connection-state=related
add action=drop chain=input comment="default configuration" in-interface=ether1-gateway
add chain=forward comment="default configuration" connection-state=established
add chain=forward comment="default configuration" connection-state=related
add action=drop chain=forward comment="default configuration" connection-state=invalid
/ip firewall nat
add action=masquerade chain=srcnat comment="default configuration" out-interface=ether1-gateway
My question, if I dont setup firewall will connections not be dropped and keep piling up until the router crashes?
Also are the scripts only executed as a script, I cannot physically type them into the terminal? Copy and paste line by line give syntax errors
I did this:
/ip firewall address-list add address=192.168.100.0/24 list=support
But when I try to remove it I get syntax errors:
[admin@MikroTik] /ip firewall address-list> remove address=192.168.100.0/24 list=support
syntax error (line 1 column 
'remove support' doesnt work either..
Sorry for being a newb
