How I access ISP router from lan side
Eth1 - wan ISP 192.168.10.1 gateway
Eth2 - pppoe server
Eth3 eth 4 - lan 192.168.88.1
Just type http://192.168.10.1 into your browser, or am I missing something?
not working this
i thin there is nat or firewall setting
Then you could connect your computer directly to your ISP’s router. If that doesn’t help, it’s some other issue we can’t help you with.
It depends on what protocol you use for the internet connection. When it is PPPoE, there will be no traffic routed towards the ethernet port unless you define an address on that.
Try to add address 192.168.10.2/24 to ether1 and a NAT masquerade rule that matches traffic to ether1.
It may be enough to add ether1 to the WAN interface list to have that (assuming you now have only pppoe-out1 in that list).
You just source NAT the LAN range to the Public IP or masquerade if the interface Public IP if it is dynamic
So in your case the static version is
/ip firewall nat
add action=src-nat chain=srcnat src-address=192.168.88.0/24 to-addresses= 192.168.10.1
The dynamic masquerade version used most where ISP IP is pppoe or dhcp AKA you wont know ISP public IP
So in your case if you didn’t know the 192.168.10.1 IP because Eth1 had a dhcp client or PPPOE client on it
/ip firewall nat
add action=masquerade chain=srcnat out-interface=Eth1 src-address=192.168.88.0/24
Both are functionally equivalent and provide a NAT between LAN and WAN
