Pozdrav!
Sliko mreze, ki jo imam najdete na http://www.sk-branik.si/ipsec.txt.
Moj cilj je iz linux2 masine dostopati do omrezja 192.168.15.0/24 preko
ipsec tunela. Na linux2 in router-ju sem uspesno prevedel in instaliral
FreeS/WAN 2.0.
Predno sem se lotil ipsec konfiguracije sem najprej preizkusil, ce dela
ping iz ene na drugo masino - iz linux2 lahko pingam router (obe kartici)
in linux1, itd. (ping dela v vse smeri iz vseh masin). Po navodilih na
http://www.freeswan.org/freeswan_trees/freeswan-2.00/doc/config.html (road
warrior configuration) sem napisal naslednja dva ipsec.conf-a :
linux2 :
conn road
left=192.168.200.2
leftnexthop=%defaultroute
leftid=@linux2.lan
leftrsasigkey=<linux2_kljuc>
right=192.168.15.100
rightsubnet=192.168.15.0/24
rightid=@router.lan
rightrsasigkey=<router_kljuc>
auto=add
router :
conn road
left=192.168.15.100
leftid=@router.lan
leftsubnet=192.168.15.0/24
leftrsasigkey=<router_kljuc>
rightnexthop=%defaultroute
right=%any
rightid=@linux2.lan
rightrsasigkey=<linux2_kljuc>
auto=add
Ko na obeh masin pozenem "service ipsec start" in na masini linux2 "ipsec
auto --up road" vidim, da sta se je ipsec tunel uspesno vzpostavil :
104 "road" #223: STATE_MAIN_I1: initiate
106 "road" #301: STATE_MAIN_I2: sent MI2, expecting MR2
108 "road" #301: STATE_MAIN_I3: sent MI3, expecting MR3
004 "road" #301: STATE_MAIN_I4: ISAKMP SA established
112 "road" #302: STATE_QUICK_I1: initiate
004 "road" #302: STATE_QUICK_I2: sent QI2, IPsec SA established
ko pa sedaj poizkusam iz linux2 pingat linux1 zadeva ne deluje. Ce med
router in linux2 postavim notebook in pozenem tcpdump vidim da grejo
kriptirani podatki (icmp request) iz smeri linux2 -> router dalje pa ne.
Kaj delam narobe?
P.S.: Na vseh treh masinah tece RH 7.3 in kernel 2.4.20.
Kakrsnakoli informacija bi bila zelo v pomoc.
Hvala in lep pozdrav,
Andrej.
