I'm installing a new security appliance 3100 on one site of my company, that has 5 ports (eth1, ..., eth5).
eth1 is connected to WAN with a public IP address
eth2 is connected to LAN with a private IP address 192.168.33.254/24 and a DHCP server for LAN clients.
192.168.33.0/24 is part of a VPN domain. Everything works well with this configuration.
Now, as it's a very small site, I'd like to use eth3, eth4 & eth5 for my LAN network too, so I would not need to use an additional switch. I created a bridge called "br1" with IP address 192.168.33.254 and added eth2 & eth3 as members.
Since, I'm not able to do anything from eth2 or eth3. I can't get an IP address, I can't reach Internet (even with a static IP address). The SmartCenter logs have entry for dropped packets with reason "Missing OS route".
My questions are:
- Is this design really supported?
- Do you have any idea about what could prevent this design from working?
Thank you in advance for your suggestions.
