Hi Gurus Recently i had change the gateway for a server i had change the IP in the /etc/defaultrouter and run the below command ```nohighlight # route add default 10.86.33.222 # route delete default 10.86.33.1 # netstat -rn Routing Table: IPv4 Destination Gateway Flags Ref Use Interface -------------------- -------------------- ----- ----- ------ --------- 10.0.0.0 10.86.33.18 U 1 4359 hme0 224.0.0.0 10.86.33.18 U 1 0 hme0 default 10.86.33.222 UG 1 0 127.0.0.1 127.0.0.1 UH 61038511 lo0 ``` when i traceroute my PC IP, it look like still use back the old route. ```nohighlight # traceroute 10.13.5.156 traceroute to 10.13.5.156 (10.13.5.156), 30 hops max, 40 byte packets 1 10.86.33.2 (10.86.33.2) 5.320 ms 0.349 ms 0.370 ms 2 10.86.32.251 (10.86.32.251) 1.568 ms 1.127 ms 1.459 ms 3 117.58.186.61 (117.58.186.61) 178.042 ms 5.784 ms 5.207 ms 4 111.92.220.61 (111.92.220.61) 37.612 ms 35.106 ms 35.186 ms 5 220.232.26.49 (220.232.26.49) 66.356 ms 65.040 ms 65.170 ms 6 220.232.26.50 (220.232.26.50) 155.544 ms 86.923 ms 109.377 ms 7 10.60.48.23 (10.60.48.23) 88.819 ms 95.388 ms 93.648 ms 8 10.60.254.22 (10.60.254.22) 239.116 ms 277.526 ms 258.929 ms 9 10.13.243.3 (10.13.243.3) 255.812 ms 241.631 ms 257.630 ms 10 * * ``` How to change the gateway without reboot the server? i cannot add a routing table, because i may use dial VPN to connect to this server. any idea ? ---

first you need to turn off ethernet ```nohighlight ifconfig hme0 down ``` then delete old route ```nohighlight route delete default 10.86.33.1 ``` add new default route ```nohighlight route add default 10.86.33.222 ``` turn on ethernet ```nohighlight ifconfig hme0 up ``` or insert line in ```nohighlight /etc/defaultrouter ``` and restart ```nohighlight svcadm restart physical ``` ---

Your method and the order you followed is wrong. Perhaps use solaris\_user steps. It should work. But NOTE\*\*\* that your network connections will definitely get disconnected for sometime (not so bad as to rebooting the server)
