I have a MT Router (2.8.11) with a 4-port Ethernet card. I'm using 2 ports, one (Public) connected to the T1 router, one (Private) connected to all the servers and radios. The 2.4ghz network is routed (Proxim MP.11) and the 900mhz network is bridged (Alvarion). All the clients have private IP's and are NAT'ed through the MT firewall. All the radios and servers have private IP's. The servers are linked to their public IP's by 1:1 NAT. (I have a /26 with the T1).
I want to get things in order before the network gets real big. I would like to put public IP's on the servers, but still run the traffic through the MT firewall. I want to be able to give public IP's to certain customers. Since they are only for management, I want to leave private IP's on all the radios.
If I understand correctly, I can add a Bridge interface that will let me put public IP's on the servers and Alvarion clients, while keeping private IP's on the radios, and still have all traffic go through the MT firewall. Will this also work for the (routed) Proxim clients, or do I continue 1:1 NAT for them. (This is working so far, but I've read it can cause trouble for clients needing to use a VPN).
Any comments, suggestions, and advice greatly appreciated.
Thanks,
Bill
I have a similair setup but with 3 interfaces.... I used the following config:
/ interface ethernet
set Internal name="Internal" mtu=1500 arp=enabled disable-running-check=yes \
auto-negotiation=yes full-duplex=yes long-cable=no speed=100Mbps \
disabled=no
set External name="External" mtu=1500 arp=enabled disable-running-check=yes \
auto-negotiation=yes full-duplex=yes long-cable=no speed=100Mbps \
disabled=no
set Management name="Management" mtu=1500 arp=enabled \
disable-running-check=yes auto-negotiation=yes full-duplex=yes \
long-cable=no speed=100Mbps disabled=no
/ interface bridge
add name="bridge1" mtu=1500 arp=enabled forward-protocols=ip,arp,ipv6,other \

disabled=no
/ interface bridge port
set Internal bridge=bridge1 priority=128 path-cost=10
set External bridge=bridge1 priority=128 path-cost=10
set Management bridge=bridge1 priority=128 path-cost=10
/ ip address
add address=10.10.10.200/24 network=10.10.10.0 broadcast=10.10.10.255 \

broadcast=XXX.124.100.127 interface=bridge1 comment="Outside Address for Natd Clients" disabled=no
Which gives me:
1. A Management Network, which has my servers on it, using both public and private addresses.
2. An Internal Network, which allows users/routers/AP's etc to access the internet via Public or Private IP's.
3. An External Network, which is directly connected to my Frame router using a cross over cable.
4. The ability to firewall the Management interface for each IP range independantly, ie VPN Access on the Private Range but not on Public etc etc.
5. Traffic Monitoring and Bandwidth Throttling for all IP's
6. NAT for the 10.10.10.0 network, using 10.10.10.200 (Private Bridge IP) for my NATed Default Gateway.
7. Direct Access to my frame router (with the router as my default gateway) for all Public IP based systems.
If it sounds like what your after, I can email you the full config file... ;)

Hmm it bounced, okay the config is below, with my public ip's edited:

Thanks, much. I really appreciate it. I'll have to print this out and look it over.
I've been using a P166 with 48mb RAM and a 2port Intel card. It worked quite well. It's now the backup router. I found a 1ghz PIII with 512mb RAM and added a Routerboard44. I plan to add a 40gb hard drive and enable the transparent web proxy. The hard part is finding some down time to do it. :D
