I have a pc with Cisco client installed that terminates on a PIX 501. when the local lan has a PIX outgoing the VPN comes up but no traffic will pass. When the local lan has a Linksys or Dlink firewall/router everything works fine I tried changing MTU, went to 576 no change, I added ipsec nat transparency on the local (originating side) no change.. outgoing PIX is wide open, no access lists etc..
any ideas?
