Re: [44net] Issue routing multiple IPs to Mikrotik

(Please trim inclusions from previous messages) _______________________________________________ Hey all, I've been trying to configure a Mikrotik router to allow devices connectivity to the Amprnet and have been running into a bit of a snag. First off here's what my architecture looks like: Internet------------->Edge Router------------>AMPR Mikrotik------------->Devices I have a public IP on the edge router and a static /29 of public IPs between the Edge router and the AMPRNet router. I have confirmed I have external access to the AMPRNet router's public IP. I followed the guide outlined by Marius here: http://www.yo2loj.ro/hamprojects/ampr-gw-README.txt and have the following WORKING as expected: 1) connectivity from the Internet to my router's 44 IP (44.135.193.129) 2) connectivity to/from the AMPRNet to my router's 44 IP 3) connectivity to/from the AMPRNet to devices behind my router (44.135.193.18) What is not working is connectivity from the Internet to devices behind the router; i.e. I am unable to PING these devices from the Internet and am unable to access any Internet resources from these devices. If I add a layer of NAT at the AMPR router, the end devices CAN access the Internet, as the source IP is concealed and appears to UCSD to be that of the 44 IP of my router (44.135.193.129). I have also tried to add an additional 44 IP to my ampr-gw IPIP interface (44.135.219.130/8) but am also unable to PING that IP from the Internet. When I look at a packet capture on the router I do not see any packets destined for this second IP making it to the router at all. Is there something special that needs to be done in order to facilitate routing to more then one 44 IP via the UCSD tunnel?
