-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, I have a server with 2 ip address 2: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 100 link/ether 00:20:ed:32:81:76 brd ff:ff:ff:ff:ff:ff inet 61.164.49.39/26 brd 61.164.49.63 scope global eth0 inet 60.12.230.167/26 brd 60.12.230.191 scope global eth0:0 and default gateway is default via 61.164.49.1 dev eth0 It works for tcp. Problem is, when client connect to 60.12.230.167 by udp, server will response the package with source ip 61.164.49.39 and client drop the packge. How should I config to make the udp response with correct source ip address? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) iD8DBQFHQP2yJo9Njjkvy34RAkJDAKDgd5mZ/WWu8btrvrOEC6ckZXCziACgzGtt k6jpYwohLyDcdTbr5AZxixQ=+/BV -----END PGP SIGNATURE-----
