Weird network problem
-
Hi All,
I have 2 pfsense 2.0.1 with IPsec site-to-site VPN tunnel configured.
LAN1 (10.25.0.0/16) <–-> FW01 <---Internet---> FW02<--> LAN2 (10.62.21.0/24)
LAN1 GW (10.25.1.1) LAN2 GW (10.62.21.1)I have allow any/any in the IPsec tunnel. All my other machine in the LAN1 network is able to ping the machine in the LAN2 network, I can also RDP to my windows server in the LAN2 network.
I have a Ubuntu server with Zoneminder software in LAN1 network with IP address 10.25.1.65 and and a network camera in LAN2 network with IP adddress 10.62.21.51. Strangely when I ping a machine in the LAN2 network for the first time, the first packet went thru but subsequence packet just cannot go thru.lawrence@sgcctv02:~$ ping 10.62.21.5
PING 10.62.21.5 (10.62.21.5) 56(84) bytes of data.
From 10.25.1.1: icmp_seq=1 Redirect Host(New nexthop: 10.62.21.5)
64 bytes from 10.62.21.5: icmp_req=1 ttl=126 time=29.6 ms
From 10.25.1.65 icmp_seq=2 Destination Host Unreachable
From 10.25.1.65 icmp_seq=3 Destination Host UnreachableI have checked on the ubuntu server and have disabled the ufw and check iptables, nothing is listed. The routing table on the ubuntu server shows:
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
0.0.0.0 10.25.1.1 0.0.0.0 UG 0 0 0 eth0
10.25.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0I have checked my firewall rules and have allowed all traffic on the LAN (any/any) on both side, still I cannot find out where is the problem. I am able to access the web cam configuration menu and view live video from LAN1 network.
Also I RDP to my windows machine in the LAN2 network and I can ping all my other servers but not the ubuntu server.
Can somebody tell me if this is an issue on the pfsense or the ubuntu server?
