Hi all,
Bit of a problem here...
Got a RB acting as a LNS in a data centre with a /24. I would like to allocate one address from this pool to an L2TP client.
Both the LNS and the client are running ROS 5.6. Both have only one ethernet port.
LNS:
IP 198.51.100.254/24
gw 198.51.100.1
Client:
ether1 IP 203.0.113.254/24
gw 203.0.113.1
I want to give the L2TP tunnel the IP address 198.51.100.253.
I can get the connection working perfectly when using addresses from a different network block (say using 192.168.0.0/24 and adding routes as appropriate), but not when I want to allocate one of the public /24s to the client. The tunnel comes up and shows the correct address, but 198.51.100.253 is not pingable/routable from anywhere other than the LNS.
In any other situation, I would configure proxy-arp on the LNSs ether1, but as soon as I do in this case, the LNS becomes unresponsive to all connections until the proxy-arp setting is removed.
Any ideas?
