Setup guide

interface may be set to MTU 1600 so that the PPPoE interface may be set to MTU 1500. This
optimizes the transmission of 1500 byte packets and avoids any problems associated with MTUs
lower than 1500. It has not been determined how to change the MTU of the Windows wireless
interface at this moment.
Let us consider the following setup where the Wandy Wireless AP offers wireless clients
transparent access to the local network with authentication:
Note that you should have Basic + Wireless + Wireless AP licenses for this setup.
First of all, the Prism interface should be configured:
[admin@MT_Prism_AP] interface prism> set 0 mode=ap-bridge frequency=2442MHz \
\... ssid=mt disabled=no
[admin@MT_Prism_AP] interface prism> print
Flags: X - disabled, R - running
0 R name="prism1" mtu=1500 mac-address=00:90:4B:02:17:E2 arp=enabled
mode=ap-bridge root-ap=00:00:00:00:00:00 frequency=2442MHz ssid="mt"
default-authentication=yes default-forwarding=yes max-clients=2007
card-type=generic tx-power=auto supported-rates=1-11 basic-rates=1
hide-ssid=no
[admin@MT_Prism_AP] interface prism> /ip address
Now, the Ethernet interface and IP address are to be set:
[admin@MT_Prism_AP] ip address> add address=10.0.0.217/24 interface=Local
[admin@MT_Prism_AP] ip address> print
Flags: X - disabled, I - invalid, D - dynamic
# ADDRESS NETWORK BROADCAST INTERFACE
0 10.0.0.217/24 10.0.0.0 10.0.0.255 Local
[admin@MT_Prism_AP] ip address> /ip route
[admin@MT_Prism_AP] ip route> add gateway=10.0.0.1
[admin@MT_Prism_AP] ip route> print
Flags: X - disabled, I - invalid, D - dynamic, J - rejected,
C - connect, S - static, R - rip, O - ospf, B - bgp
# DST-ADDRESS G GATEWAY DISTANCE INTERFACE
0 S 0.0.0.0/0 r 10.0.0.1 1 Local
1 DC 10.0.0.0/24 r 0.0.0.0 0 Local
[admin@MT_Prism_AP] ip route> /interface ethernet
[admin@MT_Prism_AP] interface ethernet> set Local arp=proxy-arp
[admin@MT_Prism_AP] interface ethernet> print
Flags: X - disabled, R - running
# NAME MTU MAC-ADDRESS ARP
0 R Local 1500 00:50:08:00:00:F5 proxy-arp
[admin@MT_Prism_AP] interface ethernet>
We should add PPPoE server to the Prism interface:
[admin@MT_Prism_AP] interface pppoe-server server> add interface=prism1 \
\... service-name=mt one-session-per-host=yes disabled=no
[admin@MT_Prism_AP] interface pppoe-server server> print
Flags: X - disabled
0 service-name="mt" interface=prism1 mtu=1480 mru=1480
authentication=mschap2,mschap,chap,pap keepalive-timeout=10
one-session-per-host=yes default-profile=default
[admin@MT_Prism_AP] interface pppoe-server server>
MSS should be changed for the packets flowing through the PPPoE link:
[admin@MT_Prism_AP] ip firewall mangle> add protocol=tcp tcp-options=syn-only \
\.. action=passthrough tcp-mss=1440
[admin@MT_Prism_AP] ip firewall mangle> print
Flags: X - disabled, I - invalid
0 src-address=0.0.0.0/0:0-65535 in-interface=all
dst-address=0.0.0.0/0:0-65535 protocol=tcp tcp-options=syn-only
icmp-options=any:any flow="" src-mac-address=00:00:00:00:00:00
limit-count=0 limit-burst=0 limit-time=0s action=passthrough
mark-flow="" tcp-mss=1440
[admin@MT_Prism_AP] ip firewall mangle>
