Router Internet Access via BGP

RouterOS Forwarding Protocols
1

I have a strange case and I can’t find a solution.

I have 2 interfaces: SFP-ISP1 and SFP-ISP2, each interface has one BGP session through a private IP.
I have a Bridge: LAN-Bridge, in this Bridge is allocated the public ip class 81.x.x.x/24 , announced through BGP

The gateway in LAN-Bridge is assigned the IP 81.x.x.1.

LAN-Bridge users can use the Internet and public IPs without any problems, but Gateway 81.x.x.1 does not, I mean the router has no internet access for itself.

(I mention that SFP-ISP1 and SFP-ISP2 are stand-alone interfaces, not part of the LAN-Bridge)

How could I make this work?

Thank you!

I solved it, who would say that sometimes ChatGPT is not a brilliant service :slight_smile:

Solution:

/routing filter rule
add chain=bgp-IN disabled=no rule=\
"if(dst in 0.0.0.0/0){set pref-src 81.x.x.1; accept;}"
