Hi
I have a problem with configuration public IP’s in LAN. My ISP give me a 2 C class of IP’s, I don’t exactly know how should to be configured routing between me and ISP. My routing configuration:

#.......DST-ADDRESS....................PREF-SRC........GATEWAY-STATE .....GATEWAY...................DISTANCE.....INTERFACE
.0.A.S..0.0.0.0/0...........................................reachable............... 123.123.100.145..................1..........ether1
.1.ADC..123.123.100.144/30.........123.123.100.146..................................................................0..........ether1
.2.ADC..123.123.90.0/23..............123.123.90.1.....................................................................0..........ether2

PC in LAN configuration: IP: 123.123.90.5 netmask: 255.255.255.0, gateway: 123.123.90.1

My ISP create /30 class betwen us.

ISP(123.123.100.145)------(123.123.100.146)eth1MTeth2(123.123.90.0-123.123.91.255)

123.123.100.145/30 ------- 123.123.100.146/30 eth1MTeth2 123.123.90.0/23

# ADDRESS NETWORK BROADCAST INTERFACE
0 123.123.100.146/30 123.123.100.144 123.123.100.147 ether1
1 123.123.90.1/23 123.123.90.0 123.123.91.255 ether2

Internet on LAN works only if i have masquerade ON, and when i test My IP on www page shows 123.123.100.146 if masquerade is OFF (NAT empty) internet not working.
Please help me create working routing.
Best Regards

B_U_L_I -

First - your LAN IP address should be (on the PC) 123.123.90.5 netmask: 255.255.0.0 (or /23)

Next, in Winbox, under /IP routes, go to rule tab, rule should be src-addr=0.0.0.0/0 dst-addr=0.0.0.0/0 action=lookup table=main

This tells ROS to lookup any IP (hence the 0.0.0.0/0) going anywhere and use table Main to route it.

Now if the above does not work then your ISP has probably not properly routed 123.123.90.0/23 to your end of the /30 connection.

R/

Your ISP should route your /23 public subnet via your IP 123.123.100.146/30 and than it should work.

Hi
I change my config as galaxynet say:

0 src-address=0.0.0.0/0 dst-address=0.0.0.0/0 routing-mark=main action=lookup table=main

PC: IP: 123.123.90.5, netmask 255.255.254.0, gateway: 123.123.90.1

Internet work's only if the masquarade is enable, if disabled nothing - NAT is empty.

What is wrong ?

Regards

B_U_L_I -
You have a routing mark in the route table. Remove the routing mark.... I never said to add a routing mark...

0 src-address=0.0.0.0/0 dst-address=0.0.0.0/0 routing-mark=main action=lookup table=main

Should be:

0 src-address=0.0.0.0/0 dst-address=0.0.0.0/0 action=lookup table=main

If it still does not work then call your ISP and verify that IP: 123.123.90.0/23 is in fact routed to 123.123.100.146

Sory my mistake. I correct and still not working. ISP has something wrong ?
Regards

B_U_L_I -

Yes - it looks to me like the ISP has not routed the IP block 123.123.90.0/23 to 123.123.100.145

If you want to make sure - then dump your config here on the forum and let's make sure everything is right....

Galaxynet I send You e-mail please look.

B_U_L_I -

Your configuration looks correct... I am guessing that your ISP has not routed your public IP block correctly.

I did not get the email - it must have gone in to my SPAM filter - please try again and I will look for it.

Hi
Problem solved. My ISP had wrong routing configuration.
THANKS THOMAS LAWLESS FOR HELP
