i have been expierencing similar issues using a config i copied and modified from a srx210 ( i made the interfaces match up) for a srx 345. the 345 is running 15.1x49-D75.5
all we are trying to do is use the 345 to support users using dhcp. the input is a router and the users will plug into the firewall.
as of now i am able to reach the firewall but i cannot get the user ports to connect.
the vlan appears to only want an irb, as i have learned from reading this thread. I used the set protocols l2-learning global-mode switch command and lost remote connectivity so i changed the firewall back to transparent to get remote connectivity restored.
im no admin, so im baffled here.
any advice would be great.
