Interface Konfiguration

WAN und LAN herausfinden und Konfigurieren

Kontrollieren welches Interface wohin geht (Mit ESXI abgleichen):

show interfaces

eth0 = WAN
eth1 = LAN

configure
set interface ethernet eth0 address '213.167.226.36/24'
set interface ethernet eth0 description 'OUTSIDE'
set interface ethernet eth1 address '10.1.1.1/24'
set interface ethernet eth1 description 'INSIDE'
set protocols static route 0.0.0.0/0 next-hop 213.167.226.1

NAT

set nat source rule 100 outbound-interface name 'eth0'
set nat source rule 100 source address '10.1.1.0/24'
set nat source rule 100 translation address masquerade

Firewall (Optional)
