Trying to setup 2 Linksys RVS4000s and having problems. I am helping a friend out who needs to setup a remote workplace. He was told to purchase the Linksys RVS4000s, so he did. He then asked for them to configure them and they didn't have anyone who did such things, so he asked me for help. I have never used one of these products before, but have done both network and Linux work in the past. Was trying to test these with a Linux box acting as a router to ensure they were working before install. The remote location is very far away. The problem that I am running into is that from the workstation I can't ping the other workstation. Also trying to ping anything on the other side of the Linux router from a workstation fails. I am also unable to ping the workstations from the Linux box, but I can ping the RVS4000s. Logged into the switch I can ping the other switch through the diagnostics page. The VPN says UP, but I can't do anything. They will be using a Mac and VOIP phone on the remote side. All IP addresses have been changed to protect the innocent This is how the Linux server is setup: This would be the office eth1 is setup as 184.108.40.206, 255.255.255.0 This would be the remote eth2 is setup as 220.127.116.11, 255.255.255.0 I have turned on ipv4 forwarding using the echo "1" > /proc/sys/net/ipv4/ip_forward. I tried installing and using firestarter but that didn't work either. I have also tried some archaic iptables forwarding and that actually made the VPN tunnel go down. I currently have iptables and selinux off to try and test this. Other settings I have tried: echo "1" > /proc/sys/net/ipv4/conf/default/rp_filter echo "1" > /proc/sys/net/ipv4/ip_dynaddr echo "1" > /proc/sys/net/ipv4/tcp_syncookies echo "1" > /proc/sys/net/ipv4/tcp_sack echo "1" > /proc/sys/net/ipv4/tcp_timestamps echo "1" > /proc/sys/net/ipv4/tcp_window_scaling echo "1" > /proc/sys/net/ipv4/ip_forward The Linksys are setup as follows: office: wan ip=18.104.22.168 nm=255.255.255.0 gw=22.214.171.124 lan ip=10.0.0.1 nm=255.255.255.0 workstation ip=10.0.0.100 nm=255.255.255.0 gw=10.0.0.1 remotewill be dhcp later, assigned static to test) wan ip=126.96.36.199 nm=255.255.255.0 gw=188.8.131.52 lan ip=10.0.0.2 nm=255.255.255.0 workstation ip=10.0.0.150 nm=255.255.255.0 gw=10.0.0.2 On the RVS4000s I have turned off the firewall, DoS Protection, and Block WAN Request. I have also disabled the IPS as well. Once I can ping the other workstation IP I will turn everything back on, I was just banging my head on the desk and wanted to make sure nothing was blocking the packets. From the workstations I can ssh into the Linux server eth port of their lan segment. So I can get into the Linux box from the workstation, just can't see the workstation from the Linux box. Any help would be greatly appreciated. Or guidance, are the RVS4000s compatible together? Do the RVS4000s by default kill ICMP requests going through them? I need to either get this working or tell them they bought incompatible hardware.
