Customer has a range of staic wan address from their ISP which basically appear on FE0/1 of a cisco 1941- we have no access at all to this router it basically just pumps out this range over Fe0/1. It goes to their ASA 5512x port 0/0 and then port 0/1 goes into their lan. I need to connect up an HP MSR VPN router using one of the statics from their WAN range to lan to lan vpn for Avaya voice traffic only. I don't have any ASA experience and their onsite guy only has very limited ASA experience (we're having trouble getting hold of their firewall maintainer) Apart from static NAT translation, (I'd prefer to be able to make the ip address of the Wan interface on HP VPN router a static ip internet address from their range provided by the ISP) They do not want a 'dumb' wan switch between their firewall and ISP router, is there any way the ASA could be configured so that if I connect my HP VPN router to one the spare ports on the ASA I can connect this straight onto the HP VPN router and manually assign a static address from their range, I would have to get thier firewall maintainer to do thism but is this actually possible?
