I have a problem with changing hardware from CISCO to Mikrotik.
I need to create a L2 tunnel for SIP traffic exchange from ISP to own Debian server, which has an IP address from /30 subnet.
Previously we had a CISCO for it and all worked fine.
How it worked on Debian:
We made a bridge
Code: Select all
brctl addbr br0
ip addr add 10.12.10.234/30 dev br0
ip link set br0 up promisc on
Code: Select all
ip l2tp add tunnel remote 214.214.214.2 local 125.125.125.125 tunnel_id 200 peer_tunnel_id 200 encap ip
ip l2tp add session tunnel_id 200 session_id 103 peer_session_id 301 l2spec_type none
ip link set dev l2tpeth0 upAfter it we add it to bridge
Code: Select all
brctl addif br0 l2tpeth0How it worked on CISCO:
