Can't add site to site VPN with existing remote access VPN 2

[wholmer]

I have an existing PIX #1 515e running 6.3(1) PDM 3.0(1) using NAT on the inside with an

existing remote client VPN set up. I need to add a site to site vpn with a PIX 515 #2 not

using NAT also running the same os.

I tried using the VPN wizard on PIX #1 and it added the following.


isakmp key ******** address 192.168.0.2 netmask 255.255.255.255 no-xauth no-config-mode
access-list inside_outbound_nat0_acl line 2 permit ip any any
nat (inside) 0 access-list inside_outbound_nat0_acl
access-list outside_cryptomap_20 permit ip any any
crypto map outside_map 20 set peer 192.168.1.2
crypto map outside_map 20 match address outside_cryptomap_20
crypto map outside_map 20 set transform-set myset
crypto map outside_map 20 set security-association lifetime seconds 28800 kilobytes 4608000
crypto map outside_map interface outside
sysopt connection permit-ipsec

It caused the PIX to not allow inside to outside and killed the existing vpn.
Can the PIX have more than one crypto map set to the outside interface?
Should I have used a different transform set than the one used on the existing vpn?
Should I use the same isakmp policy as the existing vpn?

Glad to help.
