I've tried to put together a quick image of what I'm trying to connect. Hope it makes sense.
So SRX config would be something like:
set interfaces ge-0/0/0 description "Trunk to Internet: SRX-210 (ge-0/0/0) to MOTOROLA SBG6580" set interfaces ge-0/0/0 gigether-options auto-negotiation set interfaces ge-0/0/0 unit 0 family inet address 172.20.15.254/24 set interfaces ge-0/0/1 description "SRX-210 (ge-0/0/1) to TP-LINK port 1 : Gateway for HOME_LAN" set interfaces ge-0/0/1 gigether-options auto-negotiation set interfaces ge-0/0/1 unit 0 family inet address 10.20.15.254/24 set interfaces ge-0/0/1 unit 0 family inet sampling input set interfaces ge-0/0/1 unit 0 family inet sampling output set interfaces fe-0/0/6 description "SRX-210 (fe-0/0/6) to ESXi eth2: Gateway for LAB_WORK" set interfaces fe-0/0/6 unit 0 family inet address 10.1.69.254/24 set interfaces fe-0/0/7 description "SRX-210 (fe-0/0/7) to ESXi eth3: Gateway for LAB_VULN" set interfaces fe-0/0/7 unit 0 family inet address 10.16.36.254/24
